A note for people who have not been to Katsu... If the prices do put you off, remember that it depends on what you order.
My experiences at Katsu has been great quality, generously cut fish. The menu may state that a piece of super premium yellowtail is $5. But consider this: this piece will be cut bigger than many other sushi places; and by bigger I mean about 50% bigger.
Dinner at Katsu (no alcohol) usually runs me about $40 - $60 per person and that includes a 18%-20% tip, depending on what I get. Compared to the nice dinner I had at Mirai a week ago ($90), I would much rather go to Katsu.
