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!

Food is decent, but catering with these folks is a nightmare. I came into the restaurant and discussed what we needed for our small event, and the manager said they would have the confirmation to me same day and I can pay up front. Sounds like a plan,right? WRONG. I called two more times over the next few days asking for the confirmation. Never received anything despite herpromises. It?s now the day before my event and they are closed, not answering the phone. I have no idea if they?re planning todeliver tomorrow. If the owner sees this, please cancel my order.

Steak Fajita Burrito was large and well made. Tasted great but needed some extra heat. Next time I'll ask for extra jalapeño peppers.

Service was pretty bad, and the sizes of their portions sure have decreased, while the prices have significantly increased. I understand everything going on with shrinkflation, and Sin and Grin sure took it to heart it seems. As for the experienceitself, like I said, the service was pretty bad. The owner seems to have a very specific image for servers he is going for,instead of hiring some servers with perhaps a bit more experience and abilities. Oh well, my boyfriend and I used to enjoy thisestablishment, but we will definitely go elsewhere from now on.
