We came to Circo expecting to be blown away, but sadly we were not. The restaurant is nice, the staff is attentive, and it provides an awesome view of the Bellagio fountain, but the food is not worth what you pay.
We started with their soup (beans and veggies - can't remember the name). It was nothing special.
Their buffalo mozzarella appetizer (really just a caprese) was alright. The tomatoes and the peppers made the dish. Again nothing special, but quite good when eaten with their house breads.
My husband went with the lamb dish, which he really liked. I thought it was tasty, but I didn't much feel like lamb, so I didn't take more than a bite.
I went with their scallops. The scallops were cooked well, but I did not think that they had much flavor. The white bean puree tasted like plain refried beans. Nothing there aside from the taste of beans.
Try your luck at another Italian establishment...
