I would actually want to give this place a 3.5, but am leaning more towards a 3 because we weren't wowed by this place and there are limited options on the menu.
The menu is kind of small in my opinion, but it seems that most people go there for the mussels. We started with Soup of the Day (which at this moment I can not remember, but was it was good!) and House Salad. Both were slightly above average. The main thing I liked about the House Salad was the dressing!
Then we got the mussels in the Lobster sauce and braised short ribs. Mussels were yummy and definitely be my choice if we came back. The braised short ribs were a little disappointing. It was cooked pretty well, tender and moist, but I didn't think the flavor was that good.
They also carry Anchor Steam beer here, in case you're a fan of the San Francisco brew.
