That's sad news. Sometimes you just need White Castle, and there's not much out there like it (other than other locations, and Krystal if you're being technical). I feel like White Castle and Graffiti Burger are so different that they're not really in competition, and it's nice knowing that they're both nearby options. While I haven't had Five Guys, and can't comment on the food, it wouldn't add much to the area now that Graffiti Burger is here. Not that that means they won't open one, I'd just rather something else moved in. That would be a great location for an amazing Indian or Mexican restaurant (he says hopefully).
If nothing else, given that it's a relatively historic location, I would really like to see the building saved somehow.
Actually, that could be a great location for a White Castle museum.
