Clover Food Lab is a fast food chain, founded in 2008 by MIT material science graduate and Harvard MBA Ayr Muir, which operates through food trucks and restaurants in Cambridge, Brookline, and Boston, Massachusetts, United States. The company serves a simple menu that changes day to day and with the seasons based on what is available from local farmers and includes a large mix of organic ingredients. The companys food and novel approach to business have been well reviewed in local and national press. The company began in September 2008 as one food truck serving the area around the Massachusetts Institute of Technology (MIT). As of fall 2011, Clover Food Lab had some 70 employees operating in 11 locations, including two Cambridge restaurants (Harvard Square and Inman Square) and six food trucks stationed near MIT, Boston University, Bostons South End neighborhood, Longwood Medical Area, Government Center, Boston Common, Dewey Square and other locations in greater Cambridge. The company was founded by Ayr Muir, a graduate of MIT in Material Science and Harvard Business School MBA program. Muir, a distant cousin of naturalist John Muir, has cited environmental motivations as a driving force behind the companys creation. He wishes "to shrink the ecological footprint of the food industry by making fresh, local, sustainable vegetarian food as common and convenient as the fare at Burger King or McDonalds". The companys food trucks are decommissioned and retrofitted cargo vehicles that use recycled vegetable oil to help them run. All of the companys utensils, napkins, and other items are compostable. Despite Clover Food Labs focus on local, sustainable and vegetarian food, Muir consciously avoids branding the companys food as such, fearing that "no one will eat it if we do".
