If you come to Hong Kong, you will most definitely see the many little cha chaan tengs (茶餐廳; literally, tea restaurants) in the city. If you're adventurous enough, you might even want to go in and sample some cha chaan teng fare, or at least try a milk tea (Hong Kong style!). I don't go to cha chaan tengs often, but some of these humble little outlets serve really good value food that people queue up for.
There is a coffee shop in Stanley that we often frequent on Sundays. We usually cozy up in one of their armchairs with a coffee or a chillino while we wait for the kids. Last Sunday, I'd needed to get something from one of the shops. On the way, right behind the coffee place, I'd discovered this little gem of a cha chaan teng! I'd never noticed it before and it was absolutely charming! Partly alfresco, wooden benches; plastic Coke crates as tables, plenty of antique-y bric-à-brac. It has such a throwback, old Hong Kong feel. It seems that they serve the usual cha chaan teng fare of noodles, milk tea, shumai (燒賣), etc. I don't know if it's any good, but I'd love to check it out one of these days.
