update: Yeah, it wasn't the best. They made sure the do-over was cooked way past the point of yumminess.
update: The original burger itself was brown on the outside, bright pink inside. I'd say medium-rare most of the way, rare in the corner I chose for the first nibble. They said they'd closed their grill down too early and it hadn't reheated properly by the time my order came in (1/2 hr to close) no, I didn't ask or get anything free. Shit happens.
