It can be incredibly windy at Fort Mason, seeing that it is by the Bay. There aren't many seats available within the food truck circle, but there are picnic tables just beyond it for bigger parties. A lot of families arrive and stay during the first part of the evening, and then trickle out as the sun goes down and the younger crowd moves in. It's a great place to meet with friends, or run into new people who share your love of food and the food truck movement. Live music varies every week as well.

JapaCurry offers a delicious Tonkatsu Curry, and at $8, it's a great value. Tonkatsu is breaded and fried chicken or pork cutlets. You wouldn't want to waste the spicy green curry (you can go mild if you'd like) and will probably find yourself drenching the rice in it. Most food trucks offer small portions for a pushy price, but this definitely plays fair.
El Porteño has great empanadas. $4 gets you a Pollo Empanada, whereas $5 gets you Carne or Jamon y
Queso. My favorite is their chicken (pollo) empanada, which is filled with Fulton Valley all-natural chicken, chicken chorizo, raisins, and olives.
Location: Fort Mason Center, San Francisco, every Friday from 5pm to 10pm
