Kevin went for the "famous" crabcakes at Timbuktu in Elkridge, and he didn't leave impressed, according to his post on Kevin & Ann Eat Everything. I remember enjoying my crabcake at Timbuktu, but not enough that I have been back since late 2008.
Like Kevin, I stopped at Timbuktu on the way home from BWI. Now, I think I'd stop for post-flight dinner at the Maiwand Kabob just off the BW Parkway on Arundel Mills Road. It's the same menu and same quality as the Maiwand Kabob in Columbia.
