Parkside (info and address)
Parkside is nestled amongst the chaos of Dirty 6th, but walk in and you'll find one of the best and most sophisticated happy hours. This includes not only deals on signature cocktails, but also on their raw oyster platters. Everyday from 5-6:30pm, the oyster platter is half price, which comes out to just 16 clams (pun kind-of intended). They always have fresh, juicy, East and West Coast varieties and don't mind mixing it up for you.
