This is one of my regular go-to spots for lunch. There is often a wait, but if you're willing to share a table with others, the wait is no more than 10 minutes. The owner at cash is always smiling and the service is fast. As others have said, you serve yourself with tea towards the back of the room. We usually have the wonton noodles with the greens. The wontons are huge and full of shrimp and the greens are tasty with oyster sauce on the side. For 6 dollars, this place is great value and a great alternative to many of the fast food joints. Note, this place only accepts cash.
