This, this, a thousand times this.
It’s been a long, long time since I’ve had a crabcake at a Baltimore restaurant. If I knew of a good recommendation, I’d mention it. I mainly just came in to say to avoid Phillips.
ETA: if you’re getting actual Maryland Blue Crab, especially jumbo lump, expect to pay for it. The price of crab meat has gone way up in the last few decades. If a place is offering a “Maryland jumbo lump” crabcake for less than $20 or $30, it’s almost certainly a fake (foreign meat, not jumbo lump, lots of filler, etc.).
