I am a massive fan of Japanese food and, since we were in Vegas for my birthday, I managed to convince my boyfriend to take me to Shibuya.
Although we got in quite late in the evening, the hostess said we were welcome to have dinner as long as we ordered within fifteen minutes as the kitchen was closing.
It is true that the food is incredibly expensive considering the portion sizes you receive but the quality of the dishes far outweigh the slight pain in your chest you get upon receiving the cheque.
The menu is much closer to traditional Japanese than most places so make sure to ask your waiter for suggestions- although I recommend the spicy tuna roll, the pork belly and the oyster tasting plate. If you have food allergies, speak up! The waiters here actually tell the chefs and get them to use separate stoves/cutlery for your needs... this has never happened to me before so I was extremely impressed.
Come here for a special occasion but make sure you're not starving as you will probably leave hungry due to the small sizes and big cost... but as I said earlier... it tastes AMAZING!
