Best place for crab in Baltimore? Dives OK!
I will be meeting up with an aunt and cousin for a few days in Baltimore this weekend for an event. We have Saturday totally free, and we want to get the best crab we can (a) nearby and (b) without breaking the bank. Any Baltimore-based Serious Eaters out there? What do you recommend for delicious, local crab? Crab cakes or the big buckets -- we Westerners just want crab! Dingy dive crab bars are totally OK.
For reference, we'll be staying in Linthicum Heights near the airport, so something nearby (or accessible by public transit -- does Baltimore have that?) would be preferred but not required.
Thanks in advance!
