That's fair, but when I compare foods I break them into tiers..

and try compare only in their tier.

When I was assessing where Culver's fit, one of my first thoughts was 'is this fast food or not?'.
I leaned towards fast food only because I looked over and saw they have a drive-thru, which I consider a key element to being considered fast food.

Admittedly I'm not from this area and not very familiar with them, so I'll let someone else have final say on what they're considered.

Do the Five Guys where you're at have drive-thrus?
