The funniest thing - they have one of these in Vancouver too - and it's a nostalgic fan favourite.
It's what you except - curt, efficient service, cheap meals and uninviting atmosphere. You get your fill on and move on.
I had a BBQ pork in noodle soup - a steal for $4.75. Unfortunately, we also ordered plain congee, donut fritter and some veggie stirfry. Veggie stirfry was pretty meh - and the donut fritter was stale. Bleh.
The HK milk tea/coffee I had to wash down this mediocrity... was also mediocre. But it's pretty much what you expect.
