I'm a fan of all the Biermarkt locations, purely for the reason of having such an extensive list of beers that is still enjoyable but also approachable whereas some places exclusively focus on the craft and independent brews that can be intimidating to the average drinker. While thats not a concern for myself, when going drinking in groups thats a good selling point, and for that simple fact and also having a patio, this place gets 4 stars.
I've usually ended up at this location on weeknights and its never been overly busy, so one benefit is that I've always been able to get a table, which was a toss up whenever I'd end up at the Esplanade location. I actually think I like the Esplanade interior layout more, but the patio at this King Street location as there is a bit more going on, making for better people watching.
