I stopped in here yesterday on my way home. It was clean and the place had maybe two people inside eating icecream at about 4pm. A family of five walked in the side door and cut in front of me (I was alone). They took forever deciding what they want and so finally another employee came out from the back to help me. He made my Oreo Cheesequake and I went and sat down. Other than the cheesecake peices, it was just "meh." It didn't really have a taste other than cold, if that can be considered a flavor. I was disappointed that I'd spent $3.78 on a small Blizzard, but considering how hot it was yesterday (in the 90s) I am glad I had something to cool off.
Also to be noted, this place sells food other than icecream, but it looks like all they make are hot dogs. And it reminded me of how one would heat up something at a gas station because that's exactly how they cooked the food for the group of five in ftont of me.
I did manage to get a Blizzard card out of the deal so that when I go back (or hopefully find another DQ), I can eventually get a free Blizzard.
