The second Five Guys in Howard County is hiring and appears to be outfitted except for the tables and chairs, according to a comment by Leasol and to an ad on Craiglist.
The delays at Fatburger in Elkridge taught me to never predict when a restaurant will open, but it sounds like the former Party Party Party store on Dobbin Road will be full of burgers and fries soon. The first Five Guts at the Columbia Mall seems busy when I walk past, but the ambiance (and the comments) haven't pulled me in for a bite yet.
(Update: The typo above was inadvertent. But I'm leaving it -- after being alerted by the comment below -- because it makes me laugh.)
(Update: Great wry comment below form Smirkman: "Dobbin Center is the food court of East Columbia.")
