Decent chance at making the 25th or 26th - as long as you don't mind a wife and/or toddler package in tow.
Famous Dave's Christiana or N Wilm? (didn't have a good experience first time there, though...) Timothy's is good too, never been there, like to try.
Another spot might be Jose's Border Cafe near Christiana Mall (everyone seems to know the big EAT sign). Tex mex to die for, and a nice big lot behind it.
