DON'T BOTHER.
I practically live next door to South Side and would give the food a "C" and service a "D" (generous).
The quality of the food here is really hit or miss. The house salad, burgers, and seared tuna are great, but the soups are incredibly salty and the calamari is so wrong it should be illegal.
Service is a different story. The girls here have obvious attitude problems and might possibly be some of the worst servers I've ever experienced in Cleveland. One night we waited almost 20 minutes to pay for our bill while our server flirted and did shots with some guy at the other end of the bar. i felt like we could have walked out and nobody would have noticed.
As a Tremont resident, i would recommend pretty much every other restaurant/bar in the area over South Side.
