Going to Las Vegas before seeing Holly Madison's awful Burlesque-ish show where she barely dances and the back up dancers dance better than her...this was the redemption of the evening. Koi had a very sophisticated ambiance in Las Vegas and we got lucky to sit right by the window and watched the Bellagio waterworks while we had dinner. I don't know why I just now reviewed Koi but I feel like I fell short on telling you my experience there. Service was spot on and we did not have to wait too long to get sat or too long for the food to arrive either which to me are all service points of the evening. We had the Kobe Style Filet Mignon "Toban-Yaki" Asparagus and Mushrooms. It was really amazing from the cut of the beef and the presentation. Koi was pricey in a way that the quality of food, ambiance and experiance were all great but it also wasn't breaking the bank or a surprise bill. We did not have the experience of seeing the true night life that unfolded at Koi because we went for an early dinner. I think it's worth seeing why people are rating Koi at a pretty high 4 to 5 stars. Next time I'm back in Vegas, I'm going to hit the happy hour and maybe even stay there until the night life starts. The ambiance, dinner and every thing in between was amazing. It was quite a good date night for us.
