Do you trust local restaurants to keep their community ties when they close or relocate?

Mykonos Grill, a Greek restaurant at 121 Congressional Lane in Rockville, is closing permanently after nearly 30 years in operation. Much of its menu and kitchen staff will move to the Mykonos Restaurant at Cabin John Village in Potomac.

Why it matters

The closing marks the end of a long-running Rockville dining fixture that many local diners have known for decades. Its move to a Potomac location keeps many familiar dishes and longtime kitchen staff available to customers willing to travel.

Mykonos Grill operated for nearly 30 years at 121 Congressional Lane, just off Rockville Pike, and its Potomac sister location at Cabin John Village opened in June 2025. The source does not state the exact closing date or how many employees will transfer.

The players

Angelo Mitsotakis

Co-owner and operator of Mykonos Grill, who runs the Rockville restaurant alongside his business partner.

Rodi Tzani

Co-owner and operator of Mykonos Grill, who shares ownership of the restaurant's nearly 30-year operation.

The details

Owners Angelo Mitsotakis and Rodi Tzani are closing the Rockville restaurant known for white plaster walls with blue trim and hand-painted Greek village murals. Its signature dishes, including moussaka, lamb shanks, fresh whole fish, saganaki and house-made spreads, are expected to continue at the Potomac restaurant.

Rockville diners who have relied on Mykonos Grill's moussaka and lamb shanks will need to travel to the Cabin John Village location in Potomac to order them. Longtime customers can expect the same kitchen team to prepare many familiar dishes at the new site.

The takeaway

Longtime favorites often survive a closure when their staff and recipes move with them, so diners can keep ordering the dishes they know. Checking the new location's hours and menu before visiting helps avoid a wasted trip.
