Restaurants are a part and parcel of life in many cultures as people prefer to dine out with friends and family without the hassle of cooking and having a chance to enjoy a nice meal. Sometimes the experience can go against what we have planned for any reason. Often it is the quality of food or the service that lets us down.
In case you have had such an experience, it is not a bad idea that you email the management of the restaurant to let them know about your experience.
Start the email with the sequence in which the events unfolded and how you got to the restaurant in the first place including what you ordered. Do mention the date and time for the benefit of the management.
In the second paragraph, tell the addressee about the experience and what was wrong with it. Try to fully explain your grievances with as many details as possible.
In the third and final paragraph, express your disappointment and humbly ask the required personnel to look into the matter and if possible, provide you with some sort of compensation.
