There is a gem of a place about 5 miles south of Inner Harbor in Linthicum called G & M Crabcakes. They are the very BEST, and they ship them to anywhere in the world. If you live within driving distance like I do, I recommend bringing a cooler and purchasing the crabcakes raw and cook them at home. (there are directions on their website) they are divine and puff up like a souffle. This is a big local hangout with people who know their crabcakes. Don't miss this place if you're in the area.
As a side note, they have the most wonderful coconut custard layer cake. Don't leave without a piece of that.
