In a nutshell: small, hidden (Chicago style) hot dog shop in market square.
I didn't even know this place existed for the longest time. You hear about overrated Franktuary right down the street, but no one ever talks about Yovi's. Yovi's isn't anything fancy and it offers the classic toppings, served with fries if you want. It's pretty awesome to find a Chicago hot dog right in Pittsburgh. The owner is from Chicago so whether it's authentic or not, I can't tell you for sure, but it certainly seems to be. I've never had a Chicago dog but Yovi's version was delicious. I loved all the flavors of the relish, peppers and tomato which gave it such a fresh taste. Yovi's has a few other sandwiches on the menu that I'm sure are good too, but it's hard not getting a Chicago dog because where else can you find one in Pittsburgh?? This is a great place for a quick lunch and I will definitely be back.
