There is definitely an impact, but everything is relative. There are good things about living above a restaurant. There's also the fact that how far away are you from him when you live above it? Is it one floor or 10 floors? If it is very close then first of all go and negotiate with the owner first. Now open restaurant is not as unreasonable as before. People open store certainly do not want to find trouble. You should be able to talk to him about your requirements and it should not be a problem.
If his indicators do not meet the standard is not allowed to open in the ground floor of residential buildings.
