I came out of there unhappy, insulted and ill. Me and my wife shared a bean burger and a beef burger. I ate my halves quite quickly as I was very hungry, but my wife took only a few bites of the bean burger before realizing that it tasted a bit odd, yet sour. 10 minutes after I started to feel ache in my stomach and I ended up visiting the toilet to throw up. When I complained, the waiter and the manager could not conceive that a bean burger could go bad and make me sick. That explains it all: they serve clients bean burgers kept in the fridge for weeks. I ended up paying for everything, including 12.5% gratuity. The waiter didn't even take the responsibility to talk to the manager about my complain; I had to do it myself! Stupid me. This place should be called Old Bean Burgers.
