I used to live in a nearby street and went there on different occasions (lunch, dinner, a drink in the afternoon) with different people. Service is amateurish (they do what they can but most of the time they're overwhelmed), and food is really nothing to get excited about. I often found some not-so-fresh oieces of vegetables in my salads and the dressing tasted like an industrial out-of-the botlle mix. OK it's not very expensive, but it's not any better than the canteen in my company. I understand that people like to go there for the atmosphere, but don't expect anything in the way of culinary experience.
