Wasn't expecting Circo to be so amazing but I'm a huge fan - It was wonderful service, a nice quiet atmosphere and the food was delicious. The decor is fun, and make sure you ask for a seat near the window where you can watch the Bellagio Fountains. In particular - the bolognesse was unbelievable - and also very highly recommend trying the lamb and osso bucco. Definitely one of the best in Vegas.
