Best place for lunch ON THE WAY TO Deep Creek?
I like the Park and Dine in Hancock, MD, as well as Weaver's. In Cumberland there is Diatri's (LaVale area right off I-68) but by the time you are there sometimes you don't want to stop.
I also stop at the AC&T Gas Station by the outlets in Hagerstown for some really fantastic fried chicken and country sides. It has been there forever, and they have some tables in the gas station, but it tends to be a quick convenient stop.
The Alpine Pantry off the exit for Flintstone makes good sandwiches. But, it is only carry out--there is no place to sit down. They also have the most divine baked goods--pies, sticky buns, whoopie pies. It is closed on Sundays though.
Cumberland, MD is very charming. There are several restaurants right in downtown on Baltimore Street that are good--City Lights, Manhattan Grill.
We also liked Casselman Inn in Grantsville off I-68 exit 19 (?). It is a casual sit-down restaurant. Their food is the homey, comfort kind of food. We love the white bread and apple butter they serve with everything. They have a bakery too.
Hope this is useful.
