I have tried it before with my brother and friends. I was actually not a fan of Korean foods so I rarely go to Samgyeopsal restaurant. On the other hand, I love the fact that your family is ready to try this since you know, it's a kind of new dish for them as well. I like the ham as the substitute though.
I really can't eat with much lettuce, tbh. I just want a bit of lettuce then add more rice into it. Kimchi is best to add on top as well. I'm glad you tasted and tried Samgyeopsal for the first time and with your family, too. It was awesome. Have some !PIZZA
