Finishing touches are being completed inside Cava Mezze Grill’s new Reston location, where an early August opening is planned.

The Greek and Mediterranean fast-casual restaurant (1815 Fountain Drive) will introduce itself to Reston with a free “community lunch” from noon to 2 p.m. Tuesday, Aug. 1. Lunchgoers are invited to stop in to try out the restaurant’s grain bowls, salads, pitas and more.

Meg Schiffman, Cava’s director of marketing, says the restaurant will open for regular business hours — 11 a.m. to 10 p.m. — the next day.

Cava Mezze Grill is an offshoot of Rockville-based Cava Mezze restaurant, which has five locations in Maryland, Virginia and D.C. There are currently about two dozen Cava Mezze Grill locations nationwide, with the Reston location one of about a dozen more planning to open soon. There are several other locations elsewhere in Northern Virginia, including in Tysons, Vienna and Merrifield’s Mosaic District.
