Not necessarily - it's a bit unpredictable. I was in there one night and it seemed to be 60% gay men, 40% lesbians, some couples... other times it can be mostly straight. If you're on the pull but are sick of Soho and Vauxhall I recommend getting the 185 to the bottom of Lewisham high street and going to Stonewalls. It's like a tacky provincial gay bar, very unpretentious, good for a laugh. Hopefully we'll get a decent laid-back gay pub in East D soon...
