Enhance Website, Plan Mobile Apps

I already have my hosting, domain, and a basic website. Now I want to integrate restaurant data and build intelligent features.

Requirements:
-Google Maps API Integration
Connect with Google Places API to dynamically download restaurants within a distance range from user location. Explore API options & costs (optimize requests to stay within free quota or low monthly fees).
-Restaurant Classification & Filters
Create a filtering system for cuisines: Indian, Japanese, Burger, Pizza, Italian, etc.
Build a structure to classify all restaurants retrieved from the API.
-Restaurant Detail Page
Show restaurant info: website, phone, address, distance, Google rating.
Key feature: link to restaurant menu/card (if available) to check for allergens.
Add quick links: booking (if available), website, call button.
-Allergy-Focused Rating & Review System
Users can rate restaurants with stars-
Example: Gluten-free friendly, Lactose-free friendly, Nut-free friendly.
Users can add comments about their experiences.
-Meta Tags & Allergy Tags
Auto-generate meta tags for each restaurant, showing for which allergic groups it is most suitable.
-Favorites
Allow users to save restaurants into their personal favorites list.
-UI/UX Improvements
-Clear, simple, mobile-friendly design for browsing, searching, filtering, and saving restaurants.
