The first food carts were pulled by horses, which often ate all the ingredients and were forced to earn the money back by fixing races with their friends. Gallop toward grub with this Groupon.

Baby's Badass Burgers

Before diners lay eyes on the bright-pink hull of the Baby’s Badass Burgers food truck, they may first notice its wafts of enchanting smoky grilled beef. At stops around town, the crew of burger babes serves stacked meats and condiments such as the She’s Smokin, a vision of smoked cheddar, crispy onions, and bacon doused in barbecue sauce. Co-founder Erica Cohen created their flagship burger, the Original Beauty, a combination of grilled onions, sautéed mushrooms, swiss cheese and special sauce.

The truck has achieved its own spotlight with an appearance on Entourage and by winning an episode of Food Wars, in addition to frequent stop ins from celebs who are fans. More adventurous diners can tackle the ultra-deluxe Cougar burger, which pairs aged beef with St. Andre cheese and shaved black truffles, or the half-pound Bombshell that challenges even titanium stomachs with two bacon-cheese melts for buns and taunts of “chicken” on the way down.
