Just tried a new HK Cafe this week. it's called Pit Stop on McNicoll (and Kennedy) at the foot of an apartment complex. Next to where i maid cafe used to be.
It's modern and clean and very inexpensive.
Had the curry beef brisket with rice. Very tasty and tender. The congee and noodles soups were also surprisingly good. And service was very attentive. Quality is very similar to Congee Queen.
Definitely worth a try if you are looking for a cafe that is clean and roomy.
