I'll be there, as will taco trucks & plenty of other good, cheap, mobile street food (to participate, you gotta have wheels). From the press release:
Street food, fresh summer fruits and veggies, live music, handcrafted local beers, ice cream sold from the back of a bicycle. Come find it all and more at Eat Real, a free festival, taking place August 28-30 at Jack London Square. Buy from your favorite street food vendors, pick up a ticket for the Beer Shed and sample from among the 40-something microbrews, or shop in the Market for local produce and artisanal snacks. In between the good eats, enjoy the non-stop entertainment and activities that include chef demonstrations, dance performances, bands, films, food competitions, and lots more, for free.
