We've spent a lot of time thinking about the dual nature of bars and restaurants in SF. Obviously, restaurants with great cocktail, wine, and beer programs abound in the city, but on a busy night, dedicated drinkers can usually forget about snagging a table to drink first and eat second-- with people waiting, most restaurants won't allow lingering, especially if food isn't a priority. On the flip side, it's easy to darken the door of a beloved bar all night, but when it comes time for some ballast, drinkers are usually sent out in search of that late-night slice or burrito. With that in mind, here's our list of a few places where barflies can both drink to their heart's content, with no restrictions on seating, and snag a bite without having to leave. Have a favorite we missed?
