Downtown LA is witnessing a profusion of food trucks these days, with cuisine ranging from grilled cheese to Dim Sum. I grabbed lunch from the cleverly named Patty Wagon today, and I think the mini-burgers that I had - with grilled peppers, onions and homemade ketchup - were the best I’ve ever eaten. The ground beef, from grass-fed cattle in Idaho, was unbelievably juicy and delicious. Oh, and the hand-cut fries come in two varieties: sea salt or rosemary and garlic. Hoo-whee!
