Great question — answering as the UphillTech team:
Instagram is rented land — algorithm changes and your regulars can't find you. A one-pager fixes it: today's location, menu, catering form.
Add online ordering for pickup and catering quotes. Trucks with pre-order pages do 20-40% more lunch revenue — the line moves faster.
One-pagers are our cheapest build: https://www.uphilltech.ca. Menu + location + order button, done.
