The orders kept coming Monday as Chipotle workers prepared an array of tacos and burritos for customers at the new Post Road East restaurant of the fast-expanding chain of Mexican grill fast-food eateries.

“We had our grand opening Sunday,” said John Salo, the general manager at the Westport location. He said the chain has about 2,100 restaurants in the U.S. — including Fairfield, Darien and Greenwich — with several now in London, Paris and Germany.

“We do Mexican cuisine and our big claim to fame is that we do food with integrity,” Salo said. “That’s the concept that we are trying to promote.”

He said Chipotle uses “locally sourced foods,” adding the company researches farms in the area and purchases whatever it can, “anything that’s locally grown and in season.”

The company is “committed to the very best ingredients” it can find and “preparing them by hand,” according to its website. Company leaders found that “real ingredients just taste better,” according to its publicity.

The menu includes burritos and burrito bowls; crispy corn, soft corn or soft flour tacos, and salads.

They come with a choice of meat or sofritas, salsa, guacamole, sour cream or cheese and lettuce. There is also a kid’s menu.

Salo said this is the eighth Chipotle restaurant he’s helped open. The others were in New Jersey.

He said that besides buying locally grown food items, the company also believes in hiring locals.

“We had a big turnout from the high school” of those seeking jobs, he said. “We hired about seven or eight students and recent grads” from Staples High School.

Salo said the Chipotle chain started in Colorado in 1994 and has since spread across country.

“The CEO, Steve Ells, is our inspirational leader,” Salo said. “He came up with the food integrity concept. He just wanted to change the way fast food was served.”

Chipotle, 370 Post Road East in the Compo Acres Shopping Center, is open seven days a week from 11 a.m. to 10 p.m., except holidays.
