Greek Restaurant E-Commerce Website

I am launching an e-commerce site for restaurants/bars and need it delivered entirely in Greek. The site’s main job is to let guests browse the menu, place an order online, and pay securely with a credit or debit card. Everything—buttons, system messages, emails—must appear in Greek, and the checkout flow has to feel effortless on mobile as well as desktop.

I’m open to the platform you recommend (WordPress + WooCommerce, Shopify, custom Laravel, etc.) as long as it supports:
• a clear product/menu structure with variants and add-ons
• a reliable card payment gateway that works for Greek customers
• real-time order confirmation to the kitchen and to the customer

Nice-to-have features such as customer reviews or a loyalty program can wait until a later phase, but if your solution can accommodate them easily please mention it.

Deliverables
1. Live, fully tested website on my domain/hosting
2. Secure card payment configuration, ready for production
3. Basic style guide and a short admin tutorial (video or PDF) showing how to update dishes, prices, and view orders
4. Two weeks of post-launch bug-fix support

Send over links to similar restaurant or food-service sites you’ve built, tell me which tech stack you’d use, and give me an estimated timeline to go from design sign-off to launch.
