from suntimes: With more than 500 colorful food carts adorning Portland neighborhoods, the “City of Roses” continues to blossom as Food Cart capital of the world. Earlier this summer, Budget Travel magazine ranked Portland first on its list of the world’s best street food. You’ll see tricked-out custom-made food carts, bubble carts on empty parking lots and food carts that offer bicycle delivery service. The Creme de la Creme cart on Portland’s east side serves escargot out of a converted 1960s school bus. As the food cart effort picks up traction in Chicago, local foodies have planned trips around Portland’s vibrant scene... Brett Burmeister runs the website food carts portland dot com (with 25,000 fans on Facebook) and conducts 60- to 90-minute tours of the city’s food carts.
