Wow! This is the best steakhouse in Madison. Not inexpensive but you get what you pay for. Nice wine selection, great steaks (go for the Cowboy) and bring your appetite. Four of us ordered a dozen oysters on the half shell, fresh and delicious. We also ordered the seared scallops, again delicious. My wife ordered the surf&turf and loved it. Service was excellent, attentive but not intrusive.
Overall we rated our dinner and the overall evening at The Wonder Bar a 5 star experience. We will be back soon.
