There is a chain of Don Don shops in the city, which are very successful. It focuses on japanese food and gives good value for what you pay.
In my opinion, I believe they are successful because of the following points:
1) Entrepreneurs who knows where to source the best products at good prices
2) Passing on the good price to the consumers while still making some profit
3) Timely delivery of the food (it takes them less than 1 minute to get the food out to consumers)
4) Strategically placed in places that could bring high traffic
If anyone would like to emulate their success, follow the points above and do your own research and take the big move to get into it.
