J-Town is like a mini Japanese town where they have Japanese restaurants, Japanese cosmetic shop, Japanese supermarket, and many other Japanese shops (books, appliances, golf). It's actually run by Japanese!
My mom and I mainly go into the supermarket. Their selection is similar to Chinese supermarkets. The markup here is extremely high, even higher than Chinese supermarkets (ex. T&T). The only thing they offer is the convenience of buying all Japanese things in one place.
What I really dislike about J-Town is that they sell expired food. I know expired food is still edible and usually safe, but what really bothers me is that THEY SELL EXPIRED FOOD AT EXPENSIVE PRICES!
Nevertheless we keep coming back all the time :/
