i have a soft spot for you sushi - it held me gently by the hand and introduced me to the wonderful world of japanese food in a safe way. It is also available in many locations which are untroubled by decent japanese restaurants, so i shall never say never.
When I stayed with a friend of the Lower East Side of NY, however, many years ago, and she dialed out for cheap sushi, it was delivered in a trice, and so much more delicious than anything in Yo sushi - especially a particularly wonderful eelskin ngiri - that i haven't really bothered with them since.
Much better than supermarket sushi, though.
