Well Americans grill too, though not necessarily that well. I'd say that Polish people are better at grilling than Americans, but barbecue is another experience entirely for anyone who grew up with it (some Americans mix the two terms too, but purists make a distinction).
wooo wooo wooo easy there cowboy, saying that Americans don't BBQ well is an insult, I think besides, Baseball and Football(American Football) BBQ is our pastime. Pork Ribs, Beef Ribs, Shrimp, Lobster, Fish, Chicken, Kabobs...my mouth is watering right now thinking about it. I have chickens ready to go tonight with a smokey mesquite BBQ sauce.
Basically if you can kill it, we can grill it!
