Restaurant business is not for everybody. It will take 24 hours of your time in the beginning and even after it is established, you will have to work hard day and night. Unless you have a very trustworthy manager, which is rarity, you will have to work as if you are one of the employees of the business, with added headache of an owner.

Having said that, it could be rewarding business as well. As for the chefs, you can start advertising (Sajha would be a good place). I wouldn't recommend this but some have approached Nepali chefs working at an Indian restaurant where the chef is not happy.

Know what you are getting into. Do you have enough funding, time and experience to get into this business?
