Reminds me of the time a girlfriend of mine at a nice, traditional sushi restaurant wanted something special - as in, off-menu.
The farthest this place went as far as appeasing North American palates was the "Philadelphia roll," a smoked salmon and cream cheese norimaki.
The weekend before, we had been at a different place, much more Westernized, where she had enjoyed tempura-fried rolls. Not like a shrimp tempura roll with tempura fried shrimp on the inside, but like the whole roll was tempura battered and fried.
This girl asks the server for a tempura fried Philly roll. The bespectacled, middle-aged 92 pound Japanese lady just about fell over. She stuttered, eked out a series of weak, "No... no, no no's" and blanched. I swear I saw her die a little inside.
