You can learn something by going to a small restaurant, and the restaurant is also very training. Your topic is not clearly written. I don't know what you really want to learn. Want to learn technology to open a shop? Or do you want to exercise in a restaurant and sell later?

1, if you want to exercise, I suggest that you'd better go to a bigger place, such as a big hotel, so that there are more people to contact and the environment is more complicated, which is more suitable for exercising you.

2. If you want to learn technology, then choose a small shop to do it, and learn from others' technology, business methods, business ideas, store location, main groups and gross profit. Wait, it's all things that need you to carefully analyze, record and learn.

if you don't understand, please leave a message to ask questions. I hope it helped you. Finally, I wish you success.
