Our family very much enjoys this variation of the Vietnamese dish.  The style is similar to hot pot or Korean grill.  We prepare a variety of raw veggies and meats. People sit at the table and cook the food and eat it with sauce. Unlike hot pot where the food is cooked in a big pot of broth, we cook the food at the table via an electric griddle. We then use a spring roll wrapper to wrap the food with raw veggies into a roll, which we dip into a sauce to eat.  Over the years, we've expanded from the traditional thinly sliced beef to add cuttle fish, shrimp, and fish as well.
