Like so many others that reviewed Ah Sin, I should have read the Yelp reviews before deciding to go.  After picking up my wife from a late night arrival at the airport, we were both starving.  Instead of trying to think of something to eat on the strip we decided to stick to the hotel and keep it easy.  We both love sushi, so Ah Sin should have been an easy choice.  Actually it was a big mistake.  \n\nIt's a pretty decent atmosphere, but that is all it had going for it.  It took more than five minutes for a server to greet us, even though there were ample amount of staff in the dining room.  When our server did arrive we could not understand him nor could he understand us...oh, this is going to be awesome!\n\nMy wife ordered a couple of rolls off the menu and I opted for the all-you-can-eat sushi.  I did order some of the same rolls she did off the all-you-can-eat menu (spicy tuna and shrimp tempura).  When they were served it was obvious something was wrong.  We ordered identical rolls but mine were half the size with twice the rice.  There is good business and then there is just completely screwing your customer, and it was obvious I was getting the royal treatment on this deal.  My tuna rolls tasted off, the shrimp roll had no flavor and the rice was under cooked to boot.  However, the rice in the rolls that my wife ordered was properly cooked, which only makes me ask the questions, \"how long ago were my rolls prepared?\"  By the time we got back to our room, neither of us were feeling too well.  \n\nOut of all the restaurants that we went to on our trip Ah Sin was, by far, the worst experience.
