What would you do if a guest complained about the taste of food in a restaurant?

First of all, you are a position in the restaurant.

If it's the boss, take the dish down and take it to the kitchen to ask the chef if it stinks. If so, ask the chef to make a new one. If not, just heat it up and put some other materials to copy, give it to the guests, and politely and patiently explain that this dish tastes like this when it is fried with ingredients!

See what kind of person he is.

If he is a very sentimental person, talk to the manager. He has strong communication skills and experience.

If you are an ordinary person, you can bring the dish down and heat it before serving it, and tell him that this dish is eaten like this! (premise: the food is ok)

Can't contradict guests, service industry, word of mouth is very important!

I hope I can help you!
