I just went to Rude Native in Waterloo a few days ago and our server told us that they have drinks and apps for $4 (incl tax) everyday between 4-6 and thurs-sat from 10pm-2am.

Drinks include pretty much anything you can think of- beer in bottles or on tap, cocktails, martinis, shots, wine

Apps - All of their apps (except coconut shrimp), breads, soups, salads, and sushi

They also have desserts for $4

This is the best food and drink deal that I've seen in the K-W

P.S. I tried their buds and brie and firecrackers and they were AMAZING!
