My favorite crab cakes in Baltimore are at the Ikaros Restaurant on Eastern Ave in Greektown. This place has been there for years, and has a full greek menu. The cakes are huge - 2 to an order and most people eat one and take the other home. Lots of backfin meat, firm and properly spiced. Don't be put off by the neighborhood or the outdated decor - this is the real thing for greek food. I've been to Pappa's (good), G&M (so-so), Timbukto (same size as Ikaros, but not as firm or tastey), and none can compare to these cakes. They also make a great baked seafood wrapped in Filo.
