All pretty much Laker spots but: Airport restaraunt breakfast in PUB, Enrique's in Ponca, and above all, the green chile cheesbuger in SAF. Not to mention the station agent's home cooking in LBL. We'd call in range and be answered with "You boys want some food!?"
As far as DEN goes, IMHO Que Bueno has been on a downhill slide for the last few years although their super secret 'fuego' sauce is still great. I remember Chef Jimmy's breakfast paninis fitting the Lakes Air bill as well: quick, greasy and cheap.
