It's a good Burrito joint, better than most...but it's no Burrito Boyz.
I've enjoyed Fat Bastard's numerous times, tasty burritos for sure. They have a pretty good variety of burritos and I think the have a weekly of monthly special too.
What keeps them from 5 stars? Coming from BB, the quality at FB isn't up there. The steak and shrimp is better at BB. The burritos at FB aren't wrapped tight enough sometimes. And it's more expensive than BB.
It's still better than Big Fat Burrito, Chino Locos, Chipotle. 2nd place is something to be proud of!
