Hands down my favorite restaurant in the world. The atmosphere is laid-back but cute. The twin brothers who own it are friendly, hospitable (one time they sent me a free dish because they saw me eyeing it from the sushi counter), and beyond good at what they do. They provide quality cuts of sushi presented in unique and tasty combinations for such a reasonable price in the city. You'd be doing yourself a disservice if you didn't order the chef's omakese...only $60 for 9 filling courses of the best sushi you've ever eaten! The polenta bites are my favorite dish, so I'd also recommend adding this to your omakese as they aren't included. They are also very accommodating to gluten free, vegan, and pescatarian diets. Over the holidays they host a drawing to give away 2 $150 gift cards. My out of town friends always request Kai Zan when they visit. Make sure you make a reservation well in advance.
