Brooklyns in Potomac is not bad. Not great-you-must-go-there, but OK for the area.
That place is gross. So dirty and a real lack of cleanliness when making sandwiches. Not the nicest.
Corned Beef King opened at an Exxon gas station in Olney. Probably the best corned beef and pastrami Ive had since leaving NY. It's only takeout....
