For years street food has had cultural importance worldwide, and it has become increasingly popular in the states. Exotic, sometimes unimaginably intricate creations are cranked out of the tiniest of kitchens daily. With all due respect to our fabulous chefs and restauranteurs, some of Portland's best cuisine is on the streets.
Some say the trend has been taken too far. Gourmet this, push the boundaries that... I say, the more the merrier. There are just too many carts to cover in a single diatribe, so I'll start with the goods in my 'hood, inner SE Portland.

Perierra Crêperie

Whether you're in the mood for something sweet or savory, Perierra's crisp, thin, crepes have mountains of flavor combinations. My go-to dinner crepe is the meat centric version with Italian style cured meats, gruyère and spinach, but there are plenty of veggie or vegan arrangements as well.

Inspired flavors like lavender-honey-cardamom and avocado are worth the calories the full fat milk instills.
Whiffies Fried Pies - Keeping with the sweet-or-savory theme, Whiffie's will see you through dinner or dessert, or both, if you like fried pies that much. The menu changes seasonally, and can include savory fare such as bbq beef brisket with

I munched on the pumpkin creation all last fall, and always enjoy the beef brisket - sharp and tangy, not overwhelmingly barbeque-y, and lots of gooey cheese. Pies are made to order and piping hot!
Pyro Pizza. Wood fired and delicious.

Also present, a Cajun and a Mexican mission style burrito cart. I've sampled both and have not been back to either, so I will not be gushing on. I found Bubba Bernie's offerings to be a tad dry and under-seasoned, and while the burritos at El Brasero aren't bad, there are so many superior options in this cartopia that I've found no reason to return.
Party all night, as much of Cartopia is geared toward the after hours, drunk munchies crowd and is open until 3am. But beware, most carts are closed on Mondays, so options are limited.
