Between all the yoga sculpt and darties at Fort Mason, the people of the Marina still need to eat. That’s where Blue Barn comes in. The counter-service spot is ideal for a quick, healthy-ish meal—they have salads, grain bowls, and sandwiches you can take to go or dig into on their back patio. The salads are delicious and large enough to feed two people—and the sandwiches, especially the Kickin’ Chicken with caramelized onion, bacon, and smoked gouda, are awesome.
