If you're only able to visit one place for craft beer while in San Diego than 57 Degrees is the place to go. They have an abundance of craft beers on tap. I'm not sure they have 57, but you wouldn't be able to try all 57 anyways !
You can create a flight of 5 of any of the beers on the board. Most from San Diego, California, or a close by state. Craft Beer Listing.
