My boyfriend and I chose to celebrate our 1 year anniversary at Prime Steakhouse at the Bellagio and we are so glad we did. It was wonderful! First and foremost, the food was incredible. After we shared the salmon sashimi as an appetizer, I had the seared tuna and my boyfriend had the filet mignon. Both were tender, juicy and just as we ordered. We also split the family-style side dishes, wild mushrooms and truffle mashed potatoes as sides. I insisted on the mashed potatoes after reading about how great they were on Yelp! and everyone was right - they were even better than anticipated. So creamy with a special 'bite' to them that I find impossible to describe. You really have to taste it to believe it. Drooling as I write... but I digress. Prime has an extensive wine list and the excellent staff even surprised us with a 'happy anniversary' free dessert of lava chocolate cake a la mode. Everything from the ambiance to the service to the food was perfect. The incredibly romantic view of the fountains at the Bellagio which went off frequently throughout our meal made the night even more memorable and special and the waiter didn't even complain when we asked him take a photo of us. We had a hard time getting reservations even calling a month out - we had to choose between 5:30 or 10 p.m. so I recommend making reservations as soon as you know you will be in Las Vegas and celebrating a special evening. This restaurant should be saved for special occasions though as it was a very pricey meal! But if you want to impress, this is the place to come.
