Some products / brands are only limited to a particular place. Products like Tirunelveli Iruttu kadai halwa. Its made by a family in Tirunelveli and till recently it was only available in that particular shop but now things have changed and you can order the awesome Tirunelveli Iruttu kadai halwa online. Same is the case with Charagh Din shirts. They had only one showroom throughout India, only in Mumbai. But then now its available online too.

This drink was only available in Delhi city. Not sure why it was only restricted to Delhi, was it because of lack of distribution, or to maintain the exclusivity? or to test the market?
Anyway do you remember any brands like this?
