Okay - just where out at the airport? Behind the fences? How about maybe we'll be lucky and it'll be in the building that's hosted Mildred's and countless other restaurants? That one's easy to find. But - where else is there back there?
I'm gonna take an EWAG and posit that non-commercial traffic from I-80 (Mom and Dad and the kids) made up a pretty small portion of the customers at the old location. The site was pretty un-presupposing (*hunh?) of a good meal - or, in other words, if you didn't know about it you probably didn't stop there. Truckers and other cognoscenti with time in the area knew where to go. And they'll, assuming traffic allows, will find the new location. Lots and lots of semi trucks drive down Wendover Blvd already - and if it isn't far off the main drag they can find the Cafe, too.
I hope.
