Here are a few locations I know where you can get your shoes, belts etc. repaired by "mochis"/Shoemaker.
Please note that these are not any shops but people working on the footpath.
1. Just outside Vaibhav theatre
Reach this location using above map. Look at the footpath, there is a man sitting having lots of shoes at display and will be busy in polishing/repairing shoes.
He has got very good hand at this and is most genuine in price.
2. Outside Magar Petrol Station (Bharat Petroleum)
This is just opposite to Magarpatta main gate on the footpath outside BP petrol pump/station.
He's fine for small work. But being near Magarpatta charges more and is less efficient.
Hope someone finds this information useful.
