How the wall works

Five steps. One hole. Zero small talk.

Watch for your number.

  1. 01

    Pick a tag

    Our menu hangs on the wall as cards. Pull the one you’re craving: chai, coffee, cold or signature.

  2. 02

    Ring the bell, pass it in

    Ring the bell once and slip your card through the hole. A hand takes it. That’s the whole conversation.

  3. 03

    Pay through the hole

    A QR card pops out. Scan and pay by UPI, or pass cash through. No queue, no counter, no chit-chat.

  4. 04

    Wait for the buzz

    Keep your pager close and watch the board. When it flashes and buzzes, your cup is ready.

  5. 05

    Collect from the other hole

    Your drink slides out of the second hole. Grab it, go, and tag us on Instagram @chai.cology.

Meanwhile, behind the wall

What you don’t see.

Every cup is brewed, poured and sealed to the same formula. Keep scrolling to peek in.

Step 1 of 3

Brew

Tea simmered with milk and masala, or coffee ground fresh and brewed. Both to a fixed spec: same ratio, same temperature, same time.

Step 2 of 3

Pour

Strained or pulled, poured from height and into your cup in under a minute. Then it's yours to grab.

Step 3 of 3

Sip

Chai or coffee, exactly how you had it last time. That's the whole point of a formula.

Find your cup

Mix the formula

Pick tea or coffee, then set it the way you like it. The glass fills as you go, and we'll match you to the closest formula on the menu.
