Maybe I have low expectations.. or maybe I just don't have my too cool for life hipster badge. Either way, I rather like South Side. I've only been there twice (both for lunch); first as the guest of a vendor and this past time meeting friend, but the place is fine by me!
Service can be slow, but always friendly. The food is quite yummy; they have duck on the menu so that makes me easy to please. I can recommend both the duck and goat cheese salad and the bbq duck pizza. I love that their flatbread pizzas are actually personal sized and you can order one without feeling like you need three extra people to share. My food has always been fresh and delicious.
I can't speak to the evening crowd, but lunch isn't that loud. They do lose a star for very limited seating if weather doesn't permit use of the outdoor patio. We got there at 12:15 and they said a table would be available at 1pm. We sat at the bar instead; which can be tricky with a 9 month pregnant woman, but we managed. She was able to live vicariously as the alcoholic beverages went by (I wouldn't be surprised if she had a post-labor margarita!).
