Of all the restaurants in the Gateway District, this is my favorite. The menu items are "small plates" (think tapas) intended for sharing. Everything I have ever tried has been very good. The service is great when it is not crowded, and good when it is crowded. The craft beers cover a spectrum, so you can find one you really like. In fact, their beer flights are reasonably priced so you can sample 5 of their offerings to help you decide.
My favorite dish is the pork shank. It is literally fall-off-the-bone tender, and you can tell it has not been boiled because it is so tasty.
Don't go y yourself. Take a crowd. They can handle it, and you will have lots of fun. Oh, and the bathrooms are funny.
