The Sandwich List's Real Signal: Which Chains Scale

A listicle naming the most iconic sandwich shop in every state went viral over the weekend. It includes Katz's Deli in New York and Primanti Bros. in Pennsylvania. Fun reading for a Saturday afternoon.

For anyone tracking the food-service sector, that list picks nostalgia over scale. The real story is which chains have the unit economics to serve that sandwich at 500 locations without quality dropping. Jersey Mike's has been opening stores at a pace that dwarfs the independents. Firehouse Subs, owned by Restaurant Brands International (NYSE: QSR), pushes into smaller markets with a franchise model that keeps food costs under 30% of revenue.

The list also ignores digital ordering. The iconic shops often run on cash and a paper menu. The chains winning today invested in app-based ordering and ghost kitchens during the pandemic. Potbelly (NASDAQ: PBPB) saw its digital mix rise sharply over the past three years.

The better data points for investors: same-store sales growth and store count expansion. Not Yelp ratings. The iconic shop in your state may be beloved. It is probably not the one that will survive another 50 years unless it adapts. The market already shows which model wins. Next quarter's earnings reports from Potbelly and Restaurant Brands will show which bets paid off.
