Omega Health Club, Kentish Town Road, London NW1, is a "massage parlour" which delivers a cursory massge and then,provided you pay for it, sex.

The place itself is somewhat seedy (serious smell of damp as you go down the stairs - they need to get it surveyed!) but the girls (mostly eastern European or oriental but a few Brits) are usually very friendly. They vary in attractiveness from (on a scale of 10) 2 to 7, so if you're lucky you can do very well. Early in the evening there are 4-5 girls, more later (I've never beenthere after 8pm but they are open until 5am)

Prices: £15 to enter, £60 for straight sex, rather more (negotiable) for extra time, other extras.

Conclusion: cheap and cheerful, reasonable value for money. Well, I've been back a few times, so it must be.
