After reading the other reviews Gus and Yiayia's is everything I expected and more!
Tip: I'm not sure if the address is correct; it states W Ohio Street but it's more Ridge Avenue. Head toward the the local community college you'll see a small park and well maintained tennis courts. There you'll didn't the bright orange beauty of a snow cone cart.
I love snow cones but really all about the experience and this is definitely a spot you can enjoy on your own or with a group of friends. I thought all snow cones were the same until I visited this spot. The ice has a different consistency since its hand grates from a large block. I holds the syrup perfectly and you can taste the flavor in serving from the beginning to the end. Their syrup is also unique; it taste different (in a good way) from the random the tasteless food coloring you get at other spots.
If you're in Pittsburgh this is a must stop spot!
