This place is always busy! The last time I went we had to take a 5:30pm reservation just because they were fully booked -- do make a reservation as you won't likely get a walk-in table, or may just need to wait forever.
This place feels like a chinese diner, you can tell a lot of the folks here are locals/regulars. They serve all your traditional Cantonese dishes, but also what you would have at home. Very authentic and the quality is always consistent. I've been here several times and each time we try a different dish, it always a good surprise, delightful, and very tasty!
