Had heard - great food, rude staff, always busy, can't book, and expensive. Sounded like a good place to go.
Tried to book - no, only if you are 6 people or more. OK, what's the wait time (7:00 pm on a Wednesday night), about 45 minutes, maybe. Does maybe mean more or less. Maybe means maybe.
Rude staff; on the phone - definitely.
So turned up on a Sunday at 5:30 pm (should be quiet as everybody should be at home watching the 49er's getting beaten by the Seahawks), shown straight to a table, but by 6:00 it was heaving, and a line at the door.
Overall the food was very good, so was the service, but the cost was quite expensive, for a slightly up-market Japanese restaurant in a fairly run-down shopping precinct.
Will I go back, probably not, but there again the food was good, and maybe worth the hassle.
