My memory is definitely fuzzy, but it is probably a 5 to 7 minute walk from the lift line to the door of empire burger. You have to walk past the shops at the base of the mountain, then across the street.
MiCasa is roughly the same distance (more snaking through buildings required), but I did not get the feeling that it was the sort of place most people come trudging in off of the mountain to eat lunch at. Its nicer, the food takes longer, etc. I only went to MiCasa for dinner though, so I might be wrong.
