Mash 19/21 Great Portland Street, W1 (0171-637 5555) Upstairs in the 140-seat restaurant, the toilets don't have video cameras, but they are unisex so women get the chance to harangue men in the queue with "Now you know what it's like for us!" Washing your hands can be a bit of a challenge as there are no taps (you just waft your arms about in the sink until something happens), but at least you can't lose the soap (it's jammed onto a curvaceous metal holder).

Belgo Central 50 Earlham Street, WC2 (0171-813 2233) The futuristic- style toilets in this mussels and beer restaurant are also unisex. If you are daunted by the idea, there is always an attendant to guide you through the experience and tell you that the water fountain is, indeed, where you are supposed to wash your hands.

Momo 25 Heddon St, London W1 (0171-434 4040) (pictured above) Designed by owner Momo himself, with Moroccan doors, these have been described as "the most luxurious toilets in London". The copper urinals are apparently Momo's pride and joy.

Met Bar 19 Old Park Lane, W1 (0171-447 5757) When the Met Bar first opened, the stylish toilet-roll holders went the way of restaurant ashtrays. Created by funky team United Designers who are also responsible for Lee Chapman and Lesley Ash's latest venture, Teatro, which has duck-egg blue "troughs" instead of urinals.

Pharmacy 150 Notting Hill Gate, W11 (0171-221 2442) The bar is done out like a chemist's shop with staff in white overalls. In keeping with the theme, the toilets are covered in old suppository packets and hypodermic needles.

The K Bar 82 Wardour St, W1 (0171-439 4393) The women's toilets at this new members' club have an amazing array of items on offer, not just perfume but chewing gum and dental floss, should you require it. The attendant also apparently sings to herself all evening.
