So I went there last night with my girlfriend and a friend. The waitress was quite rude and just gave a bad vibe. My burger was okay but the other two were completely messed up, and when my friend told her after he was asked how the burger was he mentioned 'it was bad'. What shocked me was her response 'but you ate it', when we asked if we can change the burgers they said that they don't have any buns left (which I personally did not believe).
