Experiences can certainly vary. My limited experience (redeeming Groupons) has been nothing but an overall positive. I went after work (5:30) so the place wasn't crowded with a lot of the DT folks that I would expect during lunch time). The folks behind the counter were friendly and personable (found out after the fact that the lady was the owner). She came out and asked how my food was. Told her while tasty, the burger I ordered was a bit on the dry side. i didn't ask for or expect anything in return, but she did offer to "make it right" by asking me if i wanted anything different (this was after I had ate the whole burger). I wanted someting else to sample so I tried the onion rings (which were some of the best I have ever had...in the top 3 for sure). On the return visit, tried something else and was pleased. I will be back.
