So is the Summit location still not open?
Edited to Add: Was really craving a burger, but didn't feel like going to a "sit down" place... so I drove out to the Summit to see if it was open... it is still under construction (but "COMING SOON"!).
Instead went and had a good burger at Shady Lane (and it wasn't the regular cook on the grill) and it satisfied my craving.
I'm still looking forward to 5 guys opening, though!
