It is not often that I hang out at Planet Hollywood, but my fiancé and I were getting ready to see Britney Spears' show and we were both very excited and eager to get to the venue. We were looking for a place to dine with his parents before the show. We had been in a sushi mood for a long time and were quite overdue. We were looking for some good, overpriced, Vegas sushi. My fiancé's mother had seen advertisements for Koi somewhere and wanted to check it out. It was very simple to make reservations, and when we got there it wasn't too busy. Of course we were eating early for Vegas standards, 6:30 PM that is. They sat us in this gorgeous, secluded area in the back that looked like a place that you would rent out or reserve for larger parties. We were excited and also curious as to how we got such a great table. Maybe because it wasn't busy and we had made a reservation. Anyway, Koi is definitely pricey but delicious sushi. We didn't order too much but we decided to make it sort of a sushi - tapas sort of experience. Each one of us would order what we thought was the best choice and then we would all share. We got the Kobe beef gyozas, Those are purely delicious. You must try those as an appetizer. There was a menu specifically for specials that they print out every night and we ordered a few things from there as well. My fiancé's father ordered an Asian whiskey that looked and tasted delicious. I have some photos below. Keep in mind the happy hour only applies if you're sitting at the bar and the lounge area. The service is excellent and the atmosphere is definitely a cool vibe. If you like sushi I know you'll love this place.
