I tried Koba with a Groupon so it was great value (pricing not bad regularly too). It's a tasty fusion combo of Korean BBQ and burritos. Not bad for a quick bite.

Approximate cost: $10

I would describe Koba is the lovechild of Mexico and Korea. The menu at Koba offers tacos, burritos and rice dishes, but the meats are prepared with a Korean tasting marinade and they also have kimchi. They have a very efficient assembly line going to serve you, and everything is under $10.
Perfect for an affordable weekday lunch.

Had lunch at Koba last week.. The food was spectacular, I could say one of the best.. I am a big fan of korean food. I had the Spicy Pork Burritos with kim chi rice (MUST TRY!), Chicken tacos and kimchi fries. Delicious. Service was super friendly and attentive staff. Highly recommended ...
