Sin Grin is a charming Main Street spot known for standout chips, queso, burritos, tacos and a memorable Mediterranean salmon, with a sunny patio and friendly bartenders that keep regulars coming. Despite tasty, reasonably priced dishes, diners report inconsistent service, shrinking portions and unreliable catering communications, which tarnish the otherwise lively, casual experience. Ideal for casual lunches, drinks and outdoor meals, it’s worth a visit—just temper expectations for large orders or flawless service.

Stopped by to check out their Steak Burrito. The best burrito I've had so far in this area. Servers/ waiters are great and the restaurant has strong social atmosphere as well. Easy to get along with. Highly recommend this place.Food: 5/5

Fantastic lunch at Sin Grin today. The chips and salsa were fantastic, as was the burrito and the tacos. I had the Mediterranean salmon special and it was phenomenal. All of this was topped off with great service. Highly recommend.

Food and atmosphere were great, but our server was truly the best part. I'm not sure I've ever seen anyone smile as much as he did, even when not in view of the customers. I'd go back just for him. So rare to see someone who seems to genuinely enjoy theirjob!
