A cautious 3 stars.
The corner spot on this patio, under the tree, is one of the very best vantage points in Kensington for people watching. Randoms will even come over and beg for money or try to have a nonsensical chat with you. Nice shade, intermittent sun and free entertainment!
Beer and bottles of wine are the way to go here. The mixed drinks are usually watered down. I always regret spending money on the food here, as it's usually a miss. The servers are among the grumpiest I've ever encountered. Not even a trace of a smile or the will to help you. They even seem pissed off that they have to bring you drinks. I blame the management. I think they're treated pretty badly by the boss, here. There's no other way to account for the fact that they're ALL having a bad day ALL the time. Obviously, it's not me-- cuz I'm awesome.
If I can get my seat on the patio, I'm all good. It's also a nice break from all the hipsters crowding all the other patios in Kensington. But be prepared for some attitude and eat before you show up here or have something planned for after.
