One of the better meals we had in LV was at FIX at Bellagio. It's a very dark bar off of the casino floor, and went in to watch the Rose Bowl and ended up staying for dinner.
I had a great roasted chicken with mashed potatoes. It must have been brined because it was quite salty, but very good. Really crispy skin.
Ken got some oysters. In Las Vegas they seem to be in season all of the time.
