No canine or feline served, but you will probably be offered chicken feet. As the carts stop at your table just ask what each dish is and, if price a concern, the price category. Items are priced A, B, C, D plus there may be one or more specials.
The more people in your party, the more dishes you will be able to sample. My wife and I usually max out at 3-4. Don't be intimidated, the carts keep rolling so try one dish and then order a second from another cart. No one will be insulted if you don't order anything from them. If you are uncomfortable using chop sticks, just ask for a fork and knife.
The first time we had dim sum was in a large, popular Chinese restaurant in Boston. Whenever a cart emerged from the kitchen, a dozen people would jump and rush to the cart. We would have starved to death if an kindly fellow diner hadn't helped us. You won't have that problem at Ping Pang Pong.
I can almost guaranty, you will have a memorable experience.
Here is a pretty good primer on dim :
