This is my favorite bar in Madison. The drinks are delish - I love the Hypnaughty, and the vodka cocktail in which you choose your own freshly muddled fruit is also divine. I haven't tried a drink there that I wouldn't order again, but I also stay away from cocktails which include chocolate or dairy products of any kind. The chips with dip were pretty tasty, though I don't go to Opus to eat. The best part about Opus, in my opinion, is how chill it is, the fact that it doesn't have a TV stuck to the wall, and how many "old" (read: over 23) people there are there.
