The term 'barbecue site, often' can be summarized by two crossword solutions: PATIO (5 letters) and YARD (4 letters). A PATIO is an outdoor space, usually paved, adjacent to a house. It is often used for entertaining, dining, or relaxation. A YARD is an open area of land, usually adjacent to a house, that is used for recreation or landscaping. Both patios and yards are popular sites for barbecues, as they provide plenty of space for grilling and seating.
