I love sushi, I love local, and I love Happy Hours. Akaihana satisfies all three and I'm there at least once a month. The happy hour menu is excellent and gives you a wide variety of things to order, from Miso Soup or Cucumber Salad for appetizer to sushi and even Saki.
You definitely can fill up on tons of Akaihana goodness on a small budget when you go during happy hour. They make delicious Jalapeno Poppers and I order them every time I'm there. My roll favorites are Tootsi and Rainbow.
The bar area is relatively small, but the table area is definitely spacious. Servers are always friendly and I have had consistently good service there.
