Dave & Andy's is the best place to get ice cream near Pitt and CMU, but that may not be saying much.
The ice cream and toppings themselves are pretty darn good. There a quite a few flavors to choose from, a bunch of toppings, and lots of menu options. Most people will find something they like.
Payment is a pain in the butt. They only accept cash. An ATM is on site, but it will charge you a few bucks for usage. This seems like tax evasion at its finest.
The atmosphere is decent. Seating is minimal and the place is slightly dirty.
Service is always friendly and fast.
Dave & Andy's is an excellent place to grab some good ice cream, but don't expect more than that.
