I only really had time to go to Harlem, which was pretty good. Music selection was really good, was blown away that the played hot nigga and I had to grab random Japanese/American guys to go ham with lol. Were a few chicks who were down to dance/grind which always makes a night great. My Japanese is decent enough to get along but most of the people there understood English well enough to ask to take photos together and one guy bought me a drink (which is the strangest feeling). Place was decently filled but not packed, so I could keep it moving and dance with different people depending on what was on.
On the downside.... Drinks felt super watered down, I'm a pretty light weight so I know for a fact that they must've been because I barely felt anything. I wanted to pre drink but I read online that Harlem had some problems in the past and banned foreigners for a bit, so I didn't drink that much to ensure I didn't get turned away. Smoking indoors is seriously terrible at least most of them seemed to stand near the back to do it, but one thing about clubs in London I love is the ability not to get someone lighting a fag next to you when you are trying to enjoy urself.
Cheers for the advice mate.
