In a month new mod Mediterranean restaurant Centro opens on Market Street in Lowell. This is what we live for. We have not had a new dining experience downtown in years. The menu is still being finalized, but chef Patty Stella, of La Boniche and the Andover Inn, has joined forces with the bartender of uber swank Beantown institute Lockobers, and that can’t be bad. The lounge/open kitchen split will give Lowell what it so badly needs, a cool place to eat, cocktail and linger over brunch on Sunday. They plan to open during Lowell Folk Festival weekend (July 27-29), failing that, Stella will be serving food out on the sidewalk during the fest. Geared toward the 30+ crowd, Centro, I expect will be a boon. The interior is aqua and brown. There will be a couch to chill and a martini glass chandelier. When it opens, expect a full report. Location is the former flower shop between the post office and Niki Tsongas’ office. If this turns out to be as good as I suspect, gourmet gal will be a regular.
