First visit January 2014, 3pm. The store was clean, lots of staff moving around in the kitchen.
I ordered the single patty burger with everything and a small drink. Total was $4.95.
The burger was room temperature, the patty was dry and thin. What I think happens is the burger was cooked but all the condiments are cold, but the patty is so thin that it drops in temperature rapidly when they wrap it in paper. When it arrives at the table the burger is slightly warmer than room temperature.
While I was eating someone in a uniform walked up to me to ask if my sandwich was okay. I had a mouthful of food at the time, which is an odd time to go interrupt someone. I wanted to ask if they could nuke my burger but by then I just wanted to leave.
The sign inside says they are open 24 hours a day. I doubt I'll return, I was totally unimpressed.
