I have a new found appreciation for Opus now that I've eaten there. I purchased a groupon for Opus for $25 which included two drinks and two plates ($50 value). My boyfriend and I went on a Friday evening around 8 and it was packed! Opus has a great "lounge" atmosphere. We ordered the crabcakes and fondue. Both were delicious. So were our drinks. Service was average. I'd definitely come back here to eat and or drink. It's such a unique place in Madison and the drinks list is eclectic! If they offer another Groupon, I'd definitely recommend it!
