One word - "quick". This is a great place if you only have half an hour but you want something cheap, sit down, and it's not a sandwich.
I have to say, this is not the best place to hang out with friends, it's more like order, eat and leave asap when you are done. It is not too clean although I haven't had any problem yet. I'm sure the food is fresh given their insane amount of turnover everyday.
my favourites:
1. Their rice dish with pork chop, sunny side-up friend egg
2. Their rice noodle (bun) with pork chop
3. also, their smoothies are good too
