Razzy has the best frozen yogurt I have ever had in Pittsburgh!!! They have many great options and do change flavors frequently. We went last night and they have some gelatos that I plan to try next time. I have tried very berry, French vanilla, pistachio, and the original which is by far my favorite!!!!! The guy working there is very friendly and he always offers punch cards!!!! I had free yogurt twice using my cards with no limit on your free one! The place doesn't close until midnight which is awesome!
