It is a little Asian grocery and yes the prices are pretty much comparable. However, they have a limited variety of things. They are more on the order of a convenience store geared towards the college students.
Their prices are ok - a little higher than the supermarkets but they have a decent selection. When we were there last month, we got tired of drinking heavy beers and they actually had cases of Bud Light cans for like $18 - if you're looking for American beer
