The name says it all.
This place is TINY, so you have to get used to eating in close quarters to other patrons. No biggie if you're used to classic small Chinese restaurants.
Make sure you order a bunch of dumplings, because it can sometimes take awhile for the stuff to be made and brought to your table, especially during peak afternoon "Dim Sum" times.
Try the lamb dumplings. It's a different item than most people are used to but is really quite tasty (if you don't mind the "lamb" taste).
If you have time on a weeknight, this place is a great place to go to have a "late" meal (meaning before 10P.M.). Great and cheap place to hang out with some good friends and have a hot, fresh, tasty (and inexpensive) meal.
