Alice Temperley at Casa Frattini, London
British designer dresses Sarah Jessica Parker and Gwyneth Paltrow

I like Casa Frattini particularly because my husband took me there on our first date. I go there with friends or for a quick dinner before my after-show parties. It's fun, with occasional lock-ins when I have been known to dance on the tables. Sometimes you can even draw on the walls. It' s not at all stuffy: no-one cranes their necks to see who else is there or stares if you mess about. Mostly though, it's just a good place to go for a quiet glass of wine and a bowl of seafood pasta. They also do the world's best tiramisu - they made us a huge one as a wedding present.

It's not a place for business - for that I would go to the Electric in Notting Hill. For a treat I go to Nobu, but I prefer it to be quiet, and not too full of people-watchers.

The most fashionable restaurant in the world has to be at Hotel Costes in Paris. I go during Paris fashion week for mashed potato and hot chocolate, and everyone else goes there too - from Kate Moss to Mick Jagger. If I don't go I end up eating nothing but Marmite on toast at show times.

I don't really like being part of the fashion crowd too much. It feels fairly awkward to me - I grew up on a cider farm and my life has always been more about cider and going to festivals than poncing around and posing. I have breakfasts at my Notting Hill studio in the summer, where we have pancakes and exotic fruits with glasses of cider. I always throw a big summer party too - fancy dress, pig roasts and more cider.

Christopher Bailey, Windsor Castle, London
The designer behind Burberry prefers pubs to 'trendy' restaurants

It's nice to escape from the fashion world and this pub is totally different: it's not precious, trendy or pretentious. I'm from Yorkshire and this reminds me of home. It's called the Windsor Castle because when it was built you could see it from the pub.

I know what they say about models and food, but the ones I know can eat me under the table. I can relate as I have always been really skinny and I eat a lot. I can't imagine ever dieting. I love the traditional food they do here - roast beef and Yorkshire pudding and sausages and mash - just like I love classic Burberry designs - our trenchcoat and the Burberry check. I moved back to the UK in 2001 to start work for Burberry, and really started to appreciate English cooking then. Before that I had my first job working in New York at Donna Karan and experienced a completely different culture in terms of eating. Then I moved to Gucci and was often in Italy, which probably has the best kitchen in the world. Two weeks ago I had lunch in an olive grove in Tuscany. I had parpadelle with hare, which was wonderful.

I come to this pub with friends - I'm so not a party person, which is why I escape here. It's much nicer to be anonymous.

I do like the Wolseley, though, because there's always a nice mix of normal people and celebrities and the menu isn't ridiculously sophisticated and overly stuck on presentation. It's the same with fashion design, you can get so involved in aesthetics that you lose sight of function.

Proenza Schouler, Freemans, New York
Jack McCollough and Lazaro Hernandez, the pair behind Proenza Schouler, love Manhattan's latest hip venue in Tribeca

The fashion business is simply littered with eating disorders. Fashion people love to celebrate though, so we often have to go to these dinners or events. The food is always awful - mass-produced stuff with terrible vegetables - but it's worth it. We saw Michelle Pfeiffer recently, and she is sooo gorgeous.

We don't really hang out with models, although a few are our friends. I always find it so bizarre at castings - those girls never eat, even after, like, five hours of fittings.

Lazaro and I love eating and right now we love Freemans. It's cool because it's hard to find, down this weird little alley and super-cute. It's secluded, which is so rare in New York. (Lazaro: 'I am redoing my house right now, and I want it to be just like Freemans. Wood floors, big fireplaces and taxidermy everywhere. It feels like Paris. It has such a cool ambience.')

Freemans does amazing steak, artichoke dip, grilled cheese, venison, shepherd's pie - the food is like an English pub's. But we do order in a lot - our studio is in Chinatown and so we get a lot of takeaway rice and pizzas.

Valentino at San Lorenzo, London
The Italian designer only eats out at lunchtime - he has his own chefs

I do come here often - at least twice a week when I am in London, but only for lunch, never dinner - frankly, eating here is like being at home - the food is simple, well-made and very good.

At home I have had the same chef for seven years. I've had English chefs, but I have always had to teach them to be a little bit Italian. My chef now is French but I've trained to him to do a sort of Mediterranean cuisine without butter or cream. He does the food for the parties I throw at my house near Paris after the catwalk shows. I have a another chef on my yacht who does different food - fish, salads and raw vegetables.

My ideal meal is quite simple - a light pasta, vegetable salad, a piece of apple or fig tart perhaps, a little red wine, some little cookies and mineral water - everything has to be made in my home although I would allow chocolates from Belgium and eat only a very few: a little self denial is healthy.

Vivia Ferragamo at Drones, London
The fashion designer granddaughter of Salvatore Ferragamo designs, works and lives between London and Florence

I grew up between England and Italy. London is my base, but as well as Florence I spend time in New York. I travel a lot so I don't have time to cook. I was in New York recently for Naomi Campbell's birthday party which was great, we ate caviar and had shots of vodka. I enjoy parties like that - although you can never have high expectations of the food. I'm OK as long as the drinks are good - I love wine - white, red, champagne. My family owns Il Borro vineyard near Arezzo and my favourite is our red Pian Di Nova. And for white I always have Prosecco in the fridge.

I do love great food though, lobster and king prawns are a favourite - I like things to be extremely splashy or very simple. I love Drones for lunch. I always have either tuna provencale, or the Drones burger and the warm chocolate tart with ice cream. I don't eat too much carbohydrate. I am blood type O, which means I feel sleepy after pasta. I do eat well though, and I make sure I eat when I am working in my studio - even if it has to be a boiled egg or some nuts. At home it will be something easy - mozzarella, parma ham, and salads. I don't have time to cook for other people and it's too stressful. I shop at an Italian deli, Luigi's on Fulham Road, and if I'm stuck for supper then I can call and they will make something for me, like chicken breast or tuna.

But mostly I find it much more relaxing to eat out with friends. Daphne's is a great place to do that. In Florence there is a great place called Vittoria, which isn't well known at all but which serves the best, freshest fish you could ever come across.
