Ok you don't come to KoKo for the food. It is average at best and overpriced. The risotto isn't very good, so don't order it...you only get one lame shrimp with it. The outdoor terrace is awesome though. On a perfect weather night it really does elevate the place.
Now I have had some good and bad experiences partying here. Sometimes I had to wait in line forever till one of my friends from inside talks with the bouncer to let me in. Another time we just walked right in. The queue outside is always ridiculously long. The most popular nights to go to KoKo are Friday nights. It will be almost impossible to get in without a table reservation.
I have bought bottles at KoKo before and they are about on par with the other clubs in Montreal with their prices, but the tables they put you at can't be called tables. They are more like appetizer sized table with just enough space to out a bottle, glasses, and mixers. They pack many people in the club too so it's almost hard to move around.
I do like the bathroom system though, definitely a plus over other clubs.
All in all, it's hit or miss and the crowd can be pretentious, but if you go in with an open mind, the music is good.
