I was in Pittsburgh for work and The Milkshake Factory was recommended to me. After walking around in the strip district, I was a bit hot and felt like a milkshake was justified with the mileage I had put in... so off I went.
I got a mint chocolate shake, which was one of the original/cheaper shake flavors. It was divine, worth every cent. The straw was sufficiently wide to get some of the chocolate chips/shreds that were in the bottom of the cup but not so big that it brought up huge gulps. The shake was about the perfect consistency, thick and creamy. By the time I got back to the hotel on foot, it was nicely thinned out from melting a bit on the trip. If I end up in Pittsburgh on business again, I would happily return for another shake.
