FIX is a restaurant located right off of the casino at the Bellagio Hotel. Service was very attentive and knowledgeable. Interestingly, FIX can host children under the age of six before 8pm. I found this to be very rewarding and a great option in a sea of restaurants that don't accept children at all. Although the music is a tad loud, it wasn't totally distracting. Concerning food quality, it was A-OK but for steaks I would recommend the dry aging not the wet aging process. A fairly decent wine list, but not a lot in the "value" range.
Good luck!
