Wicked Local CHELMSFORD -- At The Establishment restaurant, a mild spring afternoon might find customers enjoying lunch or snacks in the spacious, red-brick interior Or, some might prefer dining outside, in a courtyard near a brook, a railroad trestle, and leafy trees with a woodpecker among their tenants. Located in The Mill -- a renovated North Chelmsford factory -- The Establishment, which opened in 2017, has been a draw both for its meals, and attractive setting. But like many eateries, it has weathered the impact of the pandemic. Co-owner Laura Cowan-Greer recently spoke about The Establishment's offerings, and how challenges brought unexpected innovations.
