I was flipping through my copy of the Food Network Magazine and was interested in checking out the article called  "50 States, 50 Burgers".

So you may wonder what was MD's claim to fame burger?  It is Mother's Federal Hill Grille offers heart attack on a plate ($11)- 8-ounce patty of ground round chuck, stuffed with cheddar cheese, covered with a Cajun batter, and - are you ready for this - deep-fried.On the bright and healthy side it is fried in canola oil, which is better for you than frying in peanut oil.

The Baltimore Sun has a great picture of it.
