I ate at Prime for dinner recently. I ended up dining alone and that might affect some of the ratings. I ate the Duck L'range which was excellent. The only problem with it was that the portion was just too small (particularly for the price). I kind of felt like I needed a second entree. Sides were good too. The ambiance is amazing. Truly a stunning restaurant with great views right on the Bellagio lake.
My only gripe was the service. It was just not 5-star. Of course they sat me in the back which probably was a big reason why. Just felt like I was an after thought the whole night. Definitely disappointed there. I would like to go back and try it again and see if I get better service if I go with someone this time.
