I hear the Chinese are pretty successful at restaurants. They also keep the population of stray dogs down. An indian restaurant might take a page out of their book. jk
my advice is to make sure that you have some sort of a retreat plan. make sure that you sort out your termination details of ur contracts. not saying that you would fail, i am just saying that from my past experiences, after the earthquake in chch, our business wanted to move away, but the rent contracts tied us down. anyway good luck
One of my best friends got sick and tired of the corporate world some years back and decided to open a BBQ restaurant in Westlake Hills (wealthy close-in Austin suburb). He ended up taking a bath in red ink. The hours were far more than he'd figured on, with many hours spent on prep after the place was closed and before it opened. Unexpected expenses. You name it, and he had the problem, yet the food was great. It sounds like you're doing things on a far smaller scale than he did, but just be aware that the business is very time consuming and unpredictable. My friend lasted less than two years and lost a hell of a lot of money. Did I say the food was great? Yeah, it doesn't always matter. Me? I wouldn't do it for the world, even though both my grandmothers had diners during the Depression and were very successful at it. They also worked their fingers to the bone. Look at all the angles, and look at them again. Think about it for several days, and then look at everything again. Just know one thing, it won't be easy.
I used to go there a lot back in the day when it was very small. I went there a few months ago and it sucks now.
Rent and Location are the two of the biggest financial factors! If your rent is too high, watch out. If your location sucks same thing. Either way Ill buy something at least once.
