From a dude who can totally retrieve data off a crashed hard drive (nerd alert) and was inspired to start cooking professionally after catering some buddies' CD release party (well-rounded nerd alert!), this pop-up taqueria behind the Belmont serves chimichurri-topped specialties like a tri-tip steak taco with avocado and queso fresco, as well as the grilled-n-creamed Naked Fish (which on Saturday will be served on a bicycle?).
