Nobody walks in and asks what you serve anymore. They decide at home, on a phone, between three tabs. If your menu isn't there, you're not in the running.
A PDF is not an online menu
A blurry PDF shot of your paper menu takes ten seconds to load and needs two-finger zoom to read. On a phone that's the same as nothing. Your menu should be a page: fast, readable, with prices.
Prices included, always
Hiding prices doesn't make people call. It makes them pick the place next door that shows them. The fear of "scaring people off" costs you the exact customers who would have come.
Photos of your three best sellers
Not all forty dishes. Three real photos of the plates you're proud of, taken in your own light. That's what gets shared and remembered.
Keep it current
An out-of-date menu online is worse than none: someone orders around a dish you dropped last spring, and now the first visit starts with an apology. With a care plan, menu changes are a text message, done the same week.
