Here's what's going in the old space quoted from http://wedentondoit.com/blog/2013/5/15/mr-farris-goes-to-city-hall-may which you should definitely read and follow on FB and Twitter if you want to be in the know about Denton stuff.
"Remember how Denton County Hamburger was never open past 3pm, and no one ever knew why? Turns out the HVAC barely worked - so they just didn’t stay open longer than the AC unit could handle. Crazy huh?
On that same topic, Denton County Hamburger's square location is no more (RIP, sweet, greasy prince), but the big news of the day is that Lone Star Attitude is moving in. The head chef from Fireside Pies and Hibiscus is carefully crafting a burger concept built around a traditional burger that doesn’t include extra love sauce or throwing on a chalupa. They are spending roughly $750,000 on renovations to get it up to code, open, and running. Apparently the seat count will be up to 178 (that's a lot of seats y'all). They'll be able to accommodate all of those brand new fancy-sch'mancy seats because they will also have a rooftop patio. To get there you'll have to hop up some new stairs designed by UNT students that look like piano keys and make music as you go up. We already can’t wait to have a burger and a beer on the rooftop while watching Twilight Tunes and the sun go down... sounds kinda great doesn’t it? We hope the burgers hold up, too."
