A nice place for a quiet drink on weeknights, or for a so-intimate-you're-squashed-against-the-bass-player weekend show.
I've seen a handful of local bands play the Embassy and it's a great fun time that usually ends up being a group dance party. But the Embassy is a fun place for casual drinks too -- they've got a nice layout, a decent bar, and good prices.
One of the great places in Kensington, but definitely getting more popular every second. Patio is totally packed in the summer because it's only about 4 square feet of wood.
