Uwajimaya is the godfather of Seattle's Asian grocery stores. The new location is International district is huge and well stocked.
You can count on getting almost all of your Thai needs at Uwajimaya.
I liked the old location better, as it was less flashy and felt like you were in a different country. The new location is a little too much like Whole Foods for my tastes. If you want the feel of the old Uwajimaya, then make a stop at Viet Wah. They will have most of what you need.
