In theory, this is a great place to visit, but practically speaking, it is always so, so crowded as to be a turn-of. There are some great vendors selling artisanal products and some terrific restaurants as well, including the Mexican eatery near the water. Just expect to stand in line for 30 minutes or more to place your order wherever you end up.
Great place to visit in San Francisco. Good food, shopping and drinks. Somethings they have a farmers market day and it's great. Parking lot across street.
Great place for lunch. You can basically eat your way around the building. Can be really crowded at lunch hour and on sunny days.
