I was recently traveling by air, and happened across a handy
little sushi guide in the airlines magazine (which I promptly ripped out and
tucked in my purse). Today I see my
article theft was totally unnecessary, because the same guide is available online. A few things worth noting

1) Proper sushi etiquette dictates dipping the fish, not the
rice, in soy sauce.

2) Americans eat just over 16 pounds of fish per person per
year, while the Japanese eat 154 pounds.

3) There is a sushi spot in Boston that serves tequila and plays salsa
music (this could be my heaven).
