I went to the Grind for the first time last night with three other people who are at the Grind on the reg. The initial reason we went was to try the wings and compare them to other places. I have to hand it to the Grind, for a burger place, the wings are awesome. We each ordered a burger, Peppercorn, Nogales, Kobe and the Sweet & Spicy. The Nogales didn't wow the crowd but the other three were great. I personally had the Sweet & Spicy-amazing burger. You get a new taste with every bite and you never know if it's going to be super sweet or spicy hot! We complimented our burgers with an order of regular and sweet potato fries...both great. The three Grind veterans insisted we try the donuts. What a feast. Overall I'd go back to the grind, eat the wings and try a different burger to see what else is good there.
Enough about the food. The service was great. Not pushy or too absent. Everyone was friendly and we definitely enjoyed our meal. Great local Phoenix restaurant.
