Known for its fresh tacos, burrito bowls and substantial salads, all made to order in front of diners, Chipotle started out as a single restaurant in Denver, Colorado, in 1993. It expanded at an impressive pace and, at one point, was opening around 100 new branches a year, largely thanks to massive investment from McDonald's. Today it operates more than 3,400 restaurants, including 41 locations in Canada, 18 in the UK, six in France and two in Germany.
