Uwajimaya is located in Chinatown you cant miss it, its located across from Vulcan ventures and near the Immigration building.
Although the Uwajimaya in Seattle is the flagship store, they also have one located in Bellevue WA and Beaverton OR.
Uwajimaya is a nice place to shop with great ambience to set the mood. Their product selection is pretty diverse from Japanese, Chinese, Thai, Vietnamese, Korean, Indian, American etc.
On the price side, they are fairly above average but in some aspects you are paying for quality and not overdated/expired products like the rest of the local chinatown stores.
There customer service can be a bit better but at least the speak english.
As far as location its quite nice you can walk around to the Uwajimaya Village and eat at different ethnic cuisines and theres a japanese bookstore.
Uwajimaya offers 2 hour free parking with validation and they sometimes hold some pretty cool events....
