Dada and the Dude are the same place, two areas with different styles:
Dada is for live electronic music/The Dude is a quieter craft beer area.
The revised edition of Uncle John's does not come close to what it was. They have some of the same beers from before, but the ones we ordered were all flat with absolutely no head, and the server tried to explain that fresh kegs are like that. The small space and poor air flow makes it stuffy quickly, especially with smokers in the room (we were a group of ten with no smokers, there were only four other people, and it still felt stuffy). I haven't been to the Dada side of the operation, but in my opinion The Dude is a failure. The only reason it doesn't get only one star is because it's a sort-of new operation and they might be (hopefully) working out the long list of bugs.
