Where to open a café in Chennai

We look about 1.6 km around each area. Café customers rarely travel far on purpose, but the people passing through an area count as much as the people living in it.

In our map: about 1.6 km, counted in map hexagons around each area. That's an approximation, not a walking or driving distance.

Each driver is ranked across Chennai, then combined with these weights. The formula is open: the map shows the working for every area.

1. 1Count people walking past between 8–10 am and 4–6 pm on a weekday, and again on a Sunday.
2. 2Visit the nearest cafés and tea stalls: how full are they, and at what price per cup?
3. 3Check the licence position for the exact space (FSSAI, trade licence, fire NOC for kitchens).
4. 4Make sure there's space to sit, or a reason to take away (office tower, bus stop).
5. 5Ask whether the building allows a kitchen exhaust and gas cylinders.

• ×Underestimating the rent share: in busy areas it can eat most of the margin.

Should a café be near offices or near homes?

It depends on when you want to be busy. Near offices, weekdays carry you and Sundays are quiet. Near homes and shops, it's the reverse. The best spots mix both, which is why transit and shopping streets score well for cafés in our map.

What do you mean by an "area"?

We split Chennai into small hexagons of about 0.7 km² each. An area's picture counts what's within the reach shown for that business, not only inside the hexagon. It's an area to look in, not an address: the exact spot still needs a visit.

Where does your data come from?

Businesses from OpenStreetMap and Overture Maps, and residents from WorldPop (2020). Map data always misses some businesses, so every count is "at least". The paid report adds a live look at the listings Google shows today.

Does this tell me the rent?

No. Rent, frontage and parking need a visit. That's why every guide ends with what to check on the ground.
