Just like you're in Japan. Food is fantastic and 100% authentic. Prices are great for lunch, normal for dinner. Be sure to check the "A" and "B" lunch choices when you walk in. They're always displayed up front, with plastic wrap on them.
Some things to expect that are a little unique:
-Closed on Tuesday
-Doesn't open until 12pm, closed between lunch and dinner
-Orders come out when ready for each person, not all at once
-Small restaurant, normally pretty crowded
