All leftover foods are yours and need to be packaged up properly and kept on ice or under refrigeration once the meal service has ended.
Food shall be provided rain or shine. May I suggest you consider some type of shelter such as a pavilion or tent because too much sun or rain can ruin any event.
I do require access to electricity when having my smoker at your site. Depending on the amount of foods served 1 or 2 additional tables will be needed for serving.
Since every event is different you and I can always make adjustments to achieve just what you are looking for. Please, never hesitate to ask questions.
