had a very bad experience at the gogo lounge... i went to the bar to get me and my girlfriend a drink and while i was at the bar some guy said to be the owner (it seemed like he was) and his friend approached my girlfriend and invited her to take a shot with them knowing she was there with me because the place is small and there weren't many people there... it was disrespectful and creepy i thought... on top of that the bartender started fighting with me because apparently two dollars is not enough tip and she started yelling at me saying that i hadn't tipped her the previous two times she served me and i had!!!
besides they don't have a coat check and you don't want to just leave your stuff at the table
overall it was a bad experience and with so many good places to party in montreal i would avoid it if i were you
