Since I grew up in Japan, I have hesitations when it comes to trying Japanese restaurants in US. While majority of the Japanese restaurants in Bloomington were disappointing, Mikado was the restaurant that was closest to having an authentic Japanese experience.
Although the sushi chefs are Chinese, they make best sushi in town. Ben, the lead chef, knows how to cut and arrange sushi and sashimi on plates, and the presentation is just wonderful. Although his English is not fluent, you should talk with him when you sit at the bar and order sushi directly to him. He is very friendly and will tell you if the sushi you want is fresh or not. He will also take custom orders, as long as it's not outrageous.
Kitchen foods are average and little bit pricey, but their unaju (eel on top of rice) is unbelievably delicious! It's $19 and I know it is expensive, you should definitely try I am certain Mikado sells the best eel in Bloomington!
The restaurant itself is pretty ok'd, you can find some stains on walls and chairs, but it really doesn't matter since the food is awesome. Definitely check this place out if you are visiting Bloomington!
