I'm working in Oakland nearby today so decided I had to try it (and because the free trays of mediocre Mexican the court reporter's office provides put me to sleep).
Had the combo for $8, fried chicken burger, messy greens and agua fresca. Fried chicken with fresh slaw was good, a little bland, but even better when I asked for some of their vinegary house made hot sauce. Greens (collards I believe) were pretty flavorful without appearing to have any pork product in them. Pineapple lime agua fresca was nicely balanced, not super sweet.
If the bar is McDonald/Wendys, the food is way above that and if those were my options I'd go here 9 out of 10 times. Very enjoyable and filling lunch for $8. Ike's and Taco place next door had lines while Locol was pretty empty.
There's an Umami Burger and Trueburger within a block, so they have a lot of burger (and other cheap lunch) competition in this area.
