Can anyone point me in the direction of a restaurant or market that serves or sells Kakigori?

Thanks.

I know this is a little different, but I'll put it out there- you can find paht bing-soo everywhere in Annandale, VA.

Temari Cafe in Rockville serves it. (1043 Rockville Pike, Rockville, MD 20852)
Temari is a gem.

A very close cousin Bing Soo is serve at Le Matin de Paris on Little River TP.

I think the closest you might come to Hawaiian shaved ice is the shaved ice cart in Bethesda, which I wrote about a while back. Obviously lacking the condensed milk. As for other more Asian options with beans and the like - Bob's (both of them) is very tasty with tapioca balls and fruit, and Malaysia Kopitiam has a good version.

Thanks--do you know when the shaved ice cart starts? Is it there now?

I wish I knew. There is some mention of it on the Chowhound thread, but I don't know when his season begins. Maybe someone who is in that area more frequently can shed some light.

The shaved ice cart outside the B&N in Bethesda has returned. There is also a granita cart at the corner of George Mason and Columbia Pike in South Arlington.
