I voted Hot Dog, because generally they always taste good, whereas so often with Nachos in cheap venues, the chips are stale. (Yes, I’m bitter.) But as with so many things in life location is everything. WHERE you eat the hot dog makes all the difference.
I’m proud to say I’ve had both a Fenway Frank and Super nachos at Fenway and both were a religious experience. Nachos at Pop Warner football games are less so. Best Nachos ever? I will date myself- the counter at Woolworth’s when I was in high school. It was like stepping into a time warp walking into that place. Thick chips, sauce piled on, peppers optional.
