Mon Ami Gabi is a great place to have a brunch especially when it is nice and sunny. We decided to make reservations to this place. However, heed my advice. Don't make reservations until you know approximately what time you will come here because you may have partied the previous night and it may be difficult for you to wake up in time.
If you want the outdoor patio, there is a waitlist (first come/first serve) regardless of whether you made reservations. This waitlist is located at the front of the restaurant. In addition, when you make a reservation, at least ask them to place you as close to the front of the restaurant where you will get some sun.
Initially, they gave us a nice loaf of warm french bread. It was pretty decent with a side of butter. Then, I ordered the steak with carmelized onions in a red wine reduction. It was quite delicious and tender. We came to this because of the charming ambiance. If you are sitting by the window or outside, you have the pleasure of viewing the fountains at Bellagio.
