Many More Asian Market offers a decent selection of Asian pantries/groceries that aren't offer in other U.S. supermarket chains. Most of their goods are Chinese-based, but there are limited selection of Thai/Japanese or other Asian pantries as well. Their store is a little small and selection seemed a little limited than what I'm used to seeing in an Asian store in a larger city (just 1-2 selection of fish sauce or dimsum, for example) but I guess acceptable compared to the generally small Asian population (and as such limited availability of Asian groceries) in Pittsburgh in general.
What I like is this Asian market is more organized/relatively clean and has a convenient parking lot next to the store, so you don't have to worry about finding a place to park your car there!
