Raley's grocery stores have a food counter in some of them, including the one near my work, and one of their specialty sandwiches is called the Dagwood. No idea if anyone making it knows what it is from, but they still use the name at least.
Although now that I look it up online, it isn't there, so apparently only my local one offers that sandwich. I should fill out a comment card because whomever owns that one is awesome for that reason, sure, but mostly because he hires almost nothing else but hot college chicks to work as baggers.
