21st Amendment, San Francisco

21st Amendment (affectionately known by locals as "21A"), offers good food, reasonable prices and a generally friendly atmosphere. This large bar/restaurant is a popular after-work destination; needless to say, it can get pretty crowded when the whistle blows, especially on Fridays. If the front is too packed to get a seat, try heading to upstairs seating area, which is a great place to grab a cocktail with a view of the whole interior. Happy hour deals are to be had, and food specialties include the classic '21A Burgers' that are made with Niman Ranch beef and served with hearty fries.
