Good concept, average execution. I had a brownie with mint ice cream while my friend tried the ice cream sandwich with one chocolate chip and one double chocolate cookie with chocolate ice cream. We both felt that the (homemade) cookies were mediocre and the ice cream wasn't anything special.
It would have been two stars for the good idea and poor result, but each sandwich is only $2 so you are getting a large treat for the price. Next time I'm in Tempe I'll choose somewhere else for ice cream- there's about 5 other places on Mill Ave alone
