I love Dim Sum! I have been to this place tons of times for the past 20+ years?
It's hard to find a good Dim Sum place around the valley and I just went again today at 11am and it took 20 minutes to get a table.
The wait is because the food is good and mostly affordable as you order and they mark items on the little pink sheet that keeps track of the price of what you've ordered.
Since it's Dim Sum, and I don't have a lot of places to base it on, the place is busy and you need to let the people walking by know what you want which is unlike other places.
I don't know of a better dim sum place in the valley, I'd recommend coming here!
