I agree with EastRocker. It has some great items, but there is a bit of sticker shock. J-Mart is a great asian market. My suggestion is when you are eating at Skappo ask if the item is avaliable in the market, then go get that one item
I found it to be a little overpriced and understocked. But I do agree they are nice. The things they do have are good quality, there just isn't much of a selection. You could double up and hit the J-Mart while you are in 9th square.
