Marina O'Loughlin considers the horrors and delights of eating in restaurants over the festive season
Why you should stay away
Turkey and all the trimmings If ever there were a phrase to strike fear into the heart, it's this one. Apart from "All you can eat buffet", these words are the excuse for the most crimes committed against food in this country since Marco Pierre White first plastered Knorr stock cubes over an innocent chicken breast.
There's the stuffing, a sub-Paxo horror of clag that attaches itself to the roof of your mouth like the creature in Alien. Chipolatas with the texture of ossified rabbit droppings. Leathery roast potatoes, sugary, filling-bothering cranberry jelly, grouty bread sauce with enough clove to cure toothache. And the turkey – a greige, stringy beast, slumping exhaustedly on its bier of parsnips. It's the poultry universe's least appealing bird thrust into a limelight it deserves about as much as I deserve a Brit award. And do not even get me started on what batch catering does to sprouts. Sulphuric.
A homemade Christmas dinner can be a thing of Dickensian beauty, but restaurant versions seem to have gone through some kind of transmogrification machine last seen in The Fly. Never has any meal made me want cheese on toast more.
Christmas Day is a time for giving And giving until it hurts. The festive season is an excuse for many restaurants to get as enthusiastically loot-hungry as those vultures at Valentine's who smilingly scalp you because you're so loved-up you won't notice the extra 50 quid for the banal set meal and the "free" red rosebud. A ton a head is about par for the course before you even attempt a small sherry; and I hope they're platinum-plating the truffled chicken they're serving at Alain Ducasse at the Dorchester, given that Christmas Day lunch there costs £295 a skull.
You could, of course, go to a branch of Scoff & Banter for a mere £60 each. You could – if you fancy spending Christmas in a place with a name that makes you want to stab out your own eyes with a cracker trinket.
Other people Other people behave very strangely at this time of year. In the lead-up to Christmas, it's the office party, that arena for people who don't normally go to restaurants unless they sell bread roll "subs" by the yard and pollute the high street with a stench almost as bad as Lush's. There's crying and singing and bad party hat-wearing and fighting and snogging and vomiting – and that's just the management. Post-office party, I once tried to get a lift from one of my then board directors by kicking her Porsche really hard and saying, "Take me home, beeyatch." She kindly obliged, so I stole her lighter and gloves. It was the tequila, m'lud.
On Christmas Day itself, the mood is more sombre. Restaurants are populated by families who leap at the excuse to slope off home early to the farty torpor of The Queen and the EastEnders Christmas special, so as not to endure too long a session with barely tolerated relatives. This is an event whose curious form of melancholy cannot be punctured by any number of cheap crackers.
All Christmas puddings Here's just what you want after a gazillion-calorie lunch: a gazillion calorie dessert. I realise I'm in a minority here, but I loathe Christmas pudding, an oafish, doughy oik of a thing, reeking of antiseptic spices and gluey with fat and wrinkly fruit. And then – excellent idea – lard it up with brandy butter. I hate mince pies, too, especially if the restaurant has helpfully microwaved them so the mincemeat is about the same temperature as the sun. Bite into one of these and it will strip off layers of skin from your gob as effectively as an acid peel.
Chefs like to get creative with these kinds of things, so they give us Christmas pudding ice-cream. Or mince-pie brûlée or cupcakes. I've seen mince pie macaroons and "Christmas trifle truffles", for God's sake. Things are not quite as bad as they are in the US, though: ice-cream specialists Salt & Straw in foodie Mecca Portland, Oregon, is offering a turkey gelato. A small sliver of perfectly affiné stilton is the only sane riposte to this kind of utter nonsense.
Restaurant staff at Christmas Basically, they hate us for so many reasons. Big parties tip appallingly (see above for general behaviour). Family parties, ditto, because the last time Pa had to pay for everyone, they were lucky to get a pound note, and Ma likes a substitution or two ("Could I have the turkey, but with the gravy on the side and broccoli instead of sprouts, and don't you have custard?"); she also vibrates with tension if there's a gap of more than three minutes between courses.
As far as chefs are concerned, they're just trying to get rid of the stuff that's destined to die a lingering death while the restaurant has its annual shut-down, hence the increasingly desperate-sounding "specials". Sea bass with Pernod and cranberry, anyone? Surliness and tired food: who could resist?
Seasonal decorations This is the time of year when even the most chic of restaurants resorts to glittery kitsch. Glittery kitsch can be a wonderful, life-affirming thing if it's done with wild abandon and Rabelaisian lack of restraint: fairy lights à gogo, sparkly bunting, vast trees heaving with a thousand mismatched baubles. But Christmas doesn't lend itself to moderation. When those minimalist beige swankpots try to do festive – a few poinsettias and a single "important" bauble – the effect can deliver a bad bout of tristesse.
The restaurant decoration that lives in my memory most was at the Heron, a notoriously "authentic" Thai restaurant in west London. They'd carefully snow-sprayed several snowmen around the walls and pillars of the basement space, on to which someone – who knows, perhaps the Heron themselves? – had equally carefully sprayed large snowmen penises. Jingle balls.
Why you should dine out
Someone else takes the strain The bliss of this. The sheer, serene joy of not having to plan several weeks in advance a meal that will take about an hour to demolish to a sprouty rubble. Not having to order the Norfolk Bronze turkey or free-range goose before it's too late, not having to feed the Christmas cake at regular levels as though it were a needy, boozehound baby.
There's no need feverishly to scan magazine articles in which celebrities pretend to adore Christmas, feeling utterly inadequate that you haven't airily knocked together a Christmas lunch table that looks like a Fortnum & Mason festive window display. You don't have to pin to-do lists to the cooker hood, documents as complex as a military campaign. And, most glorious of all, there's no washing up.
No leftovers Any restraint I might pretend to practise flees in the face of Christmas leftovers. I've been known to have a Boxing Day sandwich composed of turkey, cranberry, stuffing, jellified gravy and solidified bread sauce (recommended). Hell, I've even fried up stuffing for breakfast (also recommended).
The slumpy inertia of the festivities' dog-end days means that the only exercise many of us get is slumping from the sofa to the fridge, each time coming away with a corner of brie, a chipolata or a chunk of sage and onion. If you don't have the feast, you don't have the temptation. I'll miss that sandwich, though.
Christmas spirits For 364 days of the year, I regard Bailey's Irish Cream and its league of siblings and imitators as some kind of treacly, cloying abomination: a curious tincture resistant to any form of normal inebriation. Order this from any self-respecting sommelier, and you'll be met with a sneer of Kenneth Williams-esque proportions.
But something weird happens at Christmas and suddenly I find myself quite fancying one. And the gloves are off; the sommelier will just have to bite it. You can drink what you like. Order away. Drink mulled wine until your head spins and your lips are stained cinnamony purple. I do draw the line at Advocaat, however. Especially a cocktail made with the Dutch eggy mess with a splodge of cherry brandy on top. Its name? The Burst Boil.
Christmassy restaurants There are restaurants that can imbue even the most festive-resistant curmudgeon with all the joys of the season. Wood-panelled old timers who give it gay abandon with the tinsel. Ones furnished with spitting log fires and the aroma of roasting meats, the kind of place that feels odd to visit in blazing sunlight.
I'm thinking of the likes of The Witchery in Edinburgh, a seasonal setting as enchanting as Narnia (its menu helpfully doesn't bother with turkey at all, offering instead pheasant pithiviers and roe deer). Or my beloved Rules, where they hang glittering baubles from a portrait of Maggie Thatcher and serve a stout, gooey steak and kidney pudding. Or historic Fitzbillies in Cambridge, where they've been known to deep-fry whole turkeys as enthusiastically as notorious US queen of excess, Paula Deen. (It's a surprisingly effective way of dealing with the beast.) I'll see you there. But no way am I wearing a paper crown.
