Every venue is different in what facilities offer and how flexible they are. Most of the self catering venues already have the necessary facilities, such as a kitchen. These venues also have refrigerators or ovens, so you can store and heat up your food until service time. If the venue doesn't have such facilities, you can use a portable burner, oven or stovetop to heat up the food. And if you have access to electricity in your venue, you can also use an electric warmer. We also strongly recommend getting chafing trays and ethanol gel fuel cans to keep them warm. This will make your buffet look nice and keep the food at the perfect temperature.
