Cola.vn is: QR menu - stick the code on the table, customers scan with their phone to view the menu, order dishes, transfer payments. When the owner hears "ting ting," there’s an order, no mistakes, no misses.

What already exists

For customers:

• QR menu with images + prices, scan to view
• Order dishes, select size, note "less sugar more ice"
• Pay with VietQR/PayOS right at the table
• Online ordering, delivered to your location
• Track order status directly (restaurant received / dish in preparation / done)
• View wifi directly on the menu, no need to ask
• Smart menu based on weather (refreshing items on hot days, snack suggestions on rainy days)

For restaurant owners:

• Create a restaurant in 2 minutes, no login required (manage with a secret link)
• Enable/disable out of stock items, change prices instantly - no need to reprint the menu
• QR poster: 1 code for the whole restaurant or each table has a code (know which table ordered)
• Real-time order notification + speaker reading orders using TTS
• Install like an app (PWA), receive notifications even when the web is off
• Print customizable invoices (logo, paper size, print via WiFi printer or save as PDF)
• Statistics on revenue, best-selling items, peak hours

Create a restaurant, receive orders, collect payments - for free. The Premium version (speaker reading orders, in-depth statistics) only costs 2 bottles of water if needed, but fr.ee is enough for sales.

I need everyone’s feedback:

If you are a restaurant owner: what features are missing or difficult to use?

If you are a developer/founder: looking at it, what should be removed or added?

The name, logo, restaurant creation flow… is there anything that feels "off"?

Anyone who finds this helpful, please share a hand, and if you have a restaurant, feel free to use it!
