Yeah, awesome.
A fond childhood memory of mine is walking down Penn Ave and smelling the aroma coming from Sam Bok's food carts. Since I was obviously unfamiliar with Korean cuisine at that time, I was always curious about it and I just couldn't resist those delicious aromas - and apparently neither could my Dad. I remember very vividly at just six-years of age, I was deligted when he handed me two crisp dollar bills which bought us four skewers of deliciously marinated chicken with a side of kimchi - stunning. One of my favorite family dining experiences. I was instantly a fan and went there all the time ever since. The groceries are also excellent too and very very fresh.
To me, this is what a true food cart experience is - fast, cheap, delicious. Not slow, inefficient, yuppified, self-important, and super-expensive. (read my review of grilled-cheese sandwhiches for $8)
