The brewery employs a lot of people that would not get a job in a 'regular' cafe/restaurant but who deserve a decent job nonetheless, for example people who have been in a psychiatric hospital for a while. Therefore some dumb people will post a review, complaining about the lousy service they got.
They are truly dumb! This place is a great in many different ways. It has great beers, good food, very friendly people and has a social function, both for the staff and the visittors.
