Simply put, The Grind provided one of the top five burgers I've ever eaten in my life. The peppercorn burger was piled high with toppings and as amazingly flavorful as I'd been told to expect. The service was friendly, attentive, and fast. The food was juicy, flavorful, and reasonably priced. Their hot wings were flavorful and the bread pudding made a grand end to the meal.
Though my initial order was brought out slightly off (with cheese despite my request) they cooked up a replacement in under 5 minutes and had it out to the table in no time. Similarly, when a friend's drink was a bit too bitter for her taste the bartender mixed up a second version more to her liking, but did not charge her any additional fee.
The only downside: I found the fries a tad unimpressive and overpriced. Ah well, not the reason I came here.
If you're near this end of Phoenix I'd highly reccomend giving The Grind a shot.
