I've eaten here a couple of times and have had great experiences each time. Last time I went was a few weeks ago with my mom after spending the afternoon/evening at Town Center Mall (or whatever it's called). It's right by the indoor flower garden (which is always very beautiful, elaborate, and fun to look at) and we were seated pretty quickly since we ate kinda late. I remember there being an endless line to get in on many occasions. I ordered the burger and it was incredible! I think my mom ordered breakfast or something else that came with toast, and hers was good, too. They presented some condiments in cool glass containers and small, glass jars of jam with the Bellagio logo on the lid.
I usually am there for breakfast, and it's delicious. They have a pretty good menu with classics and even some new twists on them. They serve breakfast all day, which I always think is very good for a restaurant to do.
The inside was gorgeous, too. My inner nerdiness shone through, becasue "Beauty and the Beast" was stuck in my head while I waited for my food.
Overall, I had a great time. Remember to sneak some of the little mints in your purse on the way out; they're really good. Can't wait to go back!
