I've gone back and forth on actually writing a review on this place, mostly because I hate writing negative reviews but felt my experience had to be shared. I have visited GRAZ several times. Generally staff was friendly, and the food ok. Not great, not bad, but ok. I kept giving them a shot as I prefer to support local, and so many of my fellow Yelpers seem to enjoy this place. On my last visit however, I was thoroughly disappointed. I had a Yelp check In offer that I wanted to use on my order. The man at the register seemed very upset that I had this and said it was not longer valid and "didn't know why that kept popping up". There was no apology, no offer to honor the offer, or even offer me something else for the inconvenience. Even a sincere apology would have been greatly appreciated. I'm bummed I was treated the way I was, in such a rude manner. I don't know if I am willing to give them another shot at this point, but hope they can use this review to improve on their customer service skills. BTW Yelp check In offer for them is still popping up on my app.
