Aji no Yuwaku / Temptation Taste 味の誘惑

One of the many grocery store chains in HK for Japanese food and snacks, their branches are mostly located within the shopping malls of public housing estates. Their beers are Japanese macros but they have a good selection of sakes and non-sake based plum wines (umeshu), so if you are into these sorts of stuffs it's worth a visit, especially when they are on sales. Food-wise, they also sell snacks and noodles from Taiwan, and their price can be cheaper than The 759 Store sometimes. Take a peek if you bump into one.
