Attention foodpreneurs of Madurai! How is your food business treating you?

I stay near bypass road and have seen its development for the past few yrs and I would say it is so convenient for everyone in my family to get something without venturing much into the city and also I cud easily hangout with friends for some snacks. Last 2 yrs, the food shops have increased exponentially here with many coming and shutting shops and a few of them continuing well. As someone who is looking to start a small business, I am more curious to know if these food outlets in the streets make a good business or not? I am talking abt the one which sells cakes, momos, soups, shakes and not the typical pani poori and chinese fast food kind. If any of you here has experience of running such food shops, let me know: 1. Whats your most selling menu 2. Initial investment to setup 3. How long it took to breakeven 4. One important factor for your success/failure I know food business is pretty tricky due to the huge overheads and inveatment but I guess these street outlets are sumwat easy to set and going.
