I just ate dinner at Mamie's Cafe in Aberdeen MD.
Yeah, they have great food. Can be a little hit/miss with the service, though. As a whole, maybe 2 times out of 20 or so I've had less than stellar service, but even then it wasn't poor.
The pot roast is amazing and they give you enough for lunch the next day. As always, dessert is included!
ETA-On a personal note, the owner's father was a Freemason as am I.
Awesome place. Great food, good prices, and huge portions. What's not to like?
Their meatloaf is out of this world, and the hot turkey and the hot roast beef platters are killer too. Like Humongo said, the portions are huge.
