Rol San is my go-to place for dim sum in Chinatown. Love the order from the card menu when I'm hungry and don't want the push-cart experience. Plus they serve dim sum all day. Dim sum for dinner is absolutely divine at times when the cravings hit (no I'm not pregnant, but do get food cravings from time to time).
Prices may seem a little higher than other places in Chinatown, but food quality is good as the food served is always hot and fresh and very flavourful.
Service is friendly, fast and efficient. Plus being a regular customer, I always get acknowledged promptly, but I still would have to wait for a table like all customers, so they're quite fair on the first come first serve policy. And when it's busy they would ask if customers mind sharing tables which makes for an interesting dining experience and I'm totally in favour of that. I had some fascinating conversations while seated with complete strangers.
Only one occasion so far that I dined alone which was a first at Rol San for me and the server was quite surprised as he thought I was ordering take-out, but still treated me like usual in his friendly manner. I think the fact I can speak Cantonese is always helpful and they're not judging at all, but treat everyone equally.
You know the place is good when there's always a line-up and on weekends if you're not there by 10:30am, expect a long wait for dim sum service.
