What Is a KDS? (Kitchen Display System) — Restaurant Guide

How a KDS Works

A KDS receives order data from the point-of-sale or QR ordering system the moment an order is placed. Instead of printing a paper KOT or having a waiter run to the kitchen, the order appears as a card on the kitchen screen.

Restrofi's KDS uses server-sent events (SSE) to push updates in real time — typically within a second of the guest confirming their order. There is no polling delay, no refresh required, and no risk of a missed notification.

Each order card shows the table number, items ordered, any customisations (e.g., 'no onion', 'extra spicy'), and a live elapsed-time timer. When a dish is prepared, the kitchen staff taps it done, which updates the order status for the front-of-house team.

Benefits for Indian Restaurants

Indian full-service restaurants run some of the most complex kitchens in the world — multiple stations (tandoor, curry, starters, desserts), high table counts, and peak-hour rushes that compress dozens of orders into minutes. A KDS directly addresses these challenges.

Fewer errors: orders arrive pre-typed with no handwriting ambiguity. Customisations like 'medium spice' or 'half portion' appear clearly instead of being scrawled or forgotten.

Faster service: the kitchen always knows the sequence of orders and their wait time. There is no paper backlog to sort through — the screen prioritises automatically.

Reduced noise: verbal KOTs (shouting orders into the kitchen) create a chaotic environment and contribute to errors. A KDS eliminates the need to shout.

Hardware Options: What Do You Need?

Traditional KDS units from commercial suppliers can cost ₹15,000–₹50,000 per screen. These are purpose-built waterproof/grease-resistant screens for commercial kitchens, which makes sense for very large operations.

Restrofi's KDS runs in any modern web browser. A ₹5,000–₹8,000 Android tablet mounted near the cooking station works as a fully functional KDS screen. A repurposed smartphone or even a wall-mounted TV with a browser stick works too.

For Indian restaurants running on tight margins, the browser-based approach means getting all the benefits of a KDS with zero proprietary hardware investment.

Colour-Coded Urgency Timers Explained

Colour coding is one of the most practical features of a KDS. As soon as an order is received, its card starts a timer visible to kitchen staff.

In Restrofi's KDS: green means the order is fresh and within the normal preparation window; amber means the order has been waiting longer than expected; red means the order is late and needs immediate attention.

This eliminates the need for kitchen staff to remember or manually track order sequences. The screen communicates urgency at a glance, reducing the cognitive load during a peak-hour rush.

How Restrofi's KDS Works

Every order placed through Restrofi — via QR code at the table, or manually entered by staff — is instantly visible on any open KDS screen. Multiple KDS screens can run simultaneously for different kitchen stations (e.g., one for the tandoor, one for the cold section).

Restrofi's KDS is browser-based: open the KDS URL on any device connected to the restaurant's WiFi, and it shows live orders. No app installation, no configuration, no maintenance.

When a complete table's order is ready, the kitchen taps it done. The order is marked complete in the Restrofi dashboard, and the waiter can see it's ready for service.
