Jasons is good, their meat is / was priced lower than Taste and their frozen food is always reliably frozen, unlike the *frozen / thawed sitting around for 2 hours after delivery / frozen / sat at the top of the freezer half thawed * version you get at the typical PnS, or indeed the old Taste. But it's too small for a big shop, never really been impressed by Aeon and Wellcome is averagely ok. I use the Fusion in CWB now although not perfect it's the best of the bunch.
Popwalk is not something I've been overly impressed with. OK if you like glitzy shops full of shop assistants with nothing to do. Po Lam mall is better imho having been upgraded a tad, with some reasonable international clothes shops having moved in. Shitty PnS though. NEVER, EVER buy frozen food from there.
TKO is a mini HK, you can find most stuff you want, but not all in one place, and when you go back next week the thing they had last week you absolutely loved will have vanished forever. *shrug* It's Hong Kong init.
