I've been going to Moonbean for years and is basically a staple in Kensington Market. They simple serve what people want at a reasonable price and offer good service while doing it. The place is narrow, busy and people still keep coming.
It's not pretentious or nouveau chic. It has a wide selection of beans that I buy all the time to brew at home. I've tried other beans from other places and it's either really bad, really expensive or both.
Other places may look better but certainly not better.
