Write a letter to the restaurant. In your letter

Tell them what they can do about it
Dear Mr. Lui,
I have just returned from hospital where I spent four unpleasant days on the drip because of food poisoning I believe is the result of eating unfit food at your restaurant.
You may recall the engagement party that was held there last week and the lovely dishes on offer. I distinctly remember trying the fried silk worm cocoons for which your restaurant is famed. Immediately after eating a couple I began to feel ill and could eat nothing else.
Unfortunately this situation caused me great discomfort. I could not return to work and I also did not want to spoil such a wonderful occasion by telling other guests about my bad experience. Your restaurant is regarded as the best in the city and this incident could ruin your reputation.
I suggest you speak to your kitchen staff to find out why the food was likely to lead to food poisoning. I would also appreciate some assistance with paying the hospital bill.
