This used to be my go-to place for burritos in the Core but unfortunately the quality of food and service has been steadily going doing down during 2014 and 2015.
You will get lost in the prep process unless you know exactly what you want in the order that they make the burrito. The prep line staff doesn't speak up and doesn't guide you (like Chipotle or BB), I've seen plenty of newbies get lost as the staff just stares without communicating. On the other hand, if you're pro level and decide to tweak your burrito (no rice or beans, mixed meats, multiple salsas, properly pronounce ingredient names) expected to be greeted by deers caught in headlights, even when they're not busy.
Lately I've been getting very bland rice and beans, I guess they're hoping that offering to drown your burrito with cheese and salsa will hide that (hint: doesn't work). And the meat portions keep getting smaller and smaller, a Regular would be a Small in most other places.
Finally, be weary of their salsas and guacamole, not fresh and not worth the extra charge.
