I don't think this is the way to find it. Why don't you ask the person in charge of the restaurant directly? This is not a trade secret. Talk to him and ask him to provide the contact information of the supplier, saying that he introduced you, and it will be easier for that supplier to communicate with them in the future! Everyone can benefit. When consulting, I said that I think the armchair in your restaurant is very comfortable. Ask where to order it. If he doesn't want to talk about it, he will talk about it. It is estimated that he is willing to talk about it. Anyway, he has no loss. This is my advice! Please accept!
