The quality of food matters the most at a wedding. You simply cannot choose a caterer on the basis of the reviews and their ratings. You cannot judge a book by its cover, right! Its not necessary that only branded caterers serve good quality of food, even caterers that fit in a budget can serve good food. Many caterers provide sample tasting of the food to make you sure about their quality. If the caterer your choosing refuses to do so then change your caterer and choose the ones that provide a tasting session.
