Why does daytime population matter?

Lunch customers are often workers, not residents, so a business district can have more lunch demand than its population suggests.

Yes, if they're mapped as sandwich shops. Many sub shops are franchises.

What comes with buying a sandwich shop?

Equipment, the lease, catering accounts and, for franchises, franchisor approval and any remodel requirements.

Where sandwich and sub shops may be underserved

Estimate only, not proof of demand.

Sandwich and sub shops live on lunch, so offices, schools, job sites and busy shopping corridors bring the steady weekday crowd. Catering trays for meetings and events can add larger orders. This map shows ZIP codes where sandwich and sub shops may be underserved.

Questions about sandwich / sub shop gaps

Do sub chains count?: Yes, if they're mapped as sandwich shops. Many sub shops are franchises.
What comes with buying a sandwich shop?: Equipment, the lease, catering accounts and, for franchises, franchisor approval and any remodel requirements.
