Asian groceries rock. Just so it isn't a wasted trip, here are some items of interest to look at:
Korean-style ramen -- similar to our made-in-the-USA copycats, but beware if you're spice sensitive. The flavoring will burn your lips off.
POCKY! -- What every anime fan should try at one point or another.
Variation: Giant Pocky -- Individually wrapped Pocky sticks as thick as your index finger and about the length of your forearm. I'm not kidding.
Canned coffee -- Exactly what it says. Canned iced coffee.
Crystalized ginger -- Haven't seen it in too many Asian markets, but if you can find it, get it. It's great for settling your stomach (tastes good, too).
Lychee tea -- Really, REALLY good
Gunpowder tea -- No, it isn't tea that explodes

It's green tea that's been dried so that the leaves roll up into little pellets, which makes the tea stronger since more can fit in a brew. The pellets look like gunpowder, hence the name.

Pickled ginger -- Even without the sushi, I can eat the stuff like candy.
