in china is it okay to go on a date at a fast food restaurant?

It is ok to have a date in a western fast restaurant instead of a Chinese one. Some couples or lovers would like to order a cup of juice or coffee at a western fast resto lake KFC or McDonald's to spend a whole after noon! However, it is a little noisy in Chinese fast resto and most people just leave when finish dining.

Thank you for your prompt reply. We will go to Beijing and Shangai.
