Web app - live "where to eat now" map of Berlin restaurants + owner panel

Hi,

I want to build a web app for people in Berlin who are hungry and want to know where they can eat right now. Think Google Maps, but only for food, with live open/closed status and today's specials. German and English.

WHAT DINERS SEE
- Full-screen map of Berlin with every restaurant, cafe and bar (OpenStreetMap data is fine). Pins show open / closed / no hours, live.
- Side panel: search (name, street, dish), "open now", "near me", cuisine filters, district and street filters, sort options (nearest, A-Z, open longest).
- Restaurant page: weekly hours, phone, website, photos, menu with prices, facilities (vegan, wheelchair, wifi...), places open nearby.
- Directions from my location (walk / bike / car on the map, transit via Google Maps), with arrival time and "still open when you arrive?".
- Today's specials / lunch offers, food news, favourites (no login).
- Must work well on phones (bottom sheet like Google Maps).

RESTAURANT OWNERS
- Owner asks for an account, we approve it, then the owner can edit ONLY their own restaurant: photos, description, opening hours, contact, menu and prices, and post offers / dish of the day.

ADMIN PANEL (for me and my partner)
- Approve/block owners, hide posts, review lunch offers found automatically on restaurant websites.

REQUIREMENTS
- Clean, modern design that fits a German audience. No template look.
- Fast map with 5,000 points, smooth animations.
- Secure logins and roles, safe photo uploads.
- Low running cost: free map/routing/search services where possible.
- Code I own, short setup guide, deployable on a small VPS.

PLEASE INCLUDE IN YOUR BID
- Which stack you would use and why
- Your timeline and price for the full scope

Thanks!
