When I was in Colorado, every sushi restaurant (and there were quite a few) served bay scallops with roe in a creamy sauce on top of rice wrapped horizontally with nori. A friend told me that this is called "gundam-style" because the piece ends up looking like a battleship. All the sushi restaurants I've been to in NYC serve scallop sushi as a slice of a sea scallop like a normal nigiri piece.
Anyone seen the former style around? Much appreciated.
