Nice location just opposite Woodman's. The store layout is very spacious and it's kept clean and nice. I especially like their huge selection of thinly sliced meats which is very suitable for steamboat/hot pot meals. I have also noticed they have live seafood on certain visits, though I've yet to try those. The treats from Japan are cool too, and J&P carries a wide range. Think macha pocky and the likes =) Those are still relatively rare to get in town, so I feel tempted each time I see them.
I like that they have a program where you get to accumulate points on every visit based on spending. All you have to do is to sign-up for a member card free of charge. You get to redeem for rewards like coupons after a certain number of points.
Being one of the newer asian marts J&P uses barcodes for almost all of their items. This is a great change from other asian marts who key in your purchases manually. Like a fellow Yelper pointed out it is now easier to keep track of what you buy.
