Sushi Kaji is probably the best Japanese restaurant in the city. If not, it's definitely up there. It's also probably the most expensive Japanese restaurant in the city. Sushi Kaji has a set of 2-3 tasting menu that differ in their number of courses and slightly in their content. If you're going to go, just get the most expensive course. You're going to drop a bunch of money even their cheapest course, so you may as well go all the way. My friends and I sat at the Sushi bar, and that is what you want to do. Watching the chefs cook is probably just as good as eating the food they produce. I enjoyed everything we were served. It all looked and tasted great. This is the sort of place you need a real reason to go. My advice is to find one and go already.
