When I'm in Vegas with my family and we're staying at the Bellagio, we always stop by and eat here. The coveted seating is being outside on the patio/balcony where you get an awesome view of the fountains. Weather permitting it's a cool location to sit, they do have mist during summer months to keep it cool and then heat lamps during the winter time.
I'm sure reservations are highly recommended, which can be done via opentable.
Their menus are usually changing all the time but they have great appetizers, a wide variety of different flat breads, and then entrees from pastas to seafood to steaks.
Their house bread is amazing. Lots of different types so you can't just stop with just 1. Their tapenade and olives accompany it just perfectly.
