My all-time favorite food cart at the Dane County Farmer's Market.
I vended at the market for a number of years, and Ingrid's egg and meat-stuffed crepes (or her oatmeal) were staples for me on those chilly Saturday mornings.
The crepes aren't super-cheap, but they're large enough to serve as two meals.
They come in both savory versions (stuffed with eggs and your choice of meats and/or veggies) or sweet (different fruit & spice combos, which change seasonally, and are often topped in fresh-whipped cream.)
