Enjoy your meal in the AC. Then once everyone is finished eating, bring them outside for some dessert by candlelight and enjoy the final stretch of cool outdoor nights.
When you order up BBQ, there is always the inclination to bring it out to the backyard. So, give in and do it! Lay out some place settings and empty out the cartons of delivery onto a big platter so everyone can share.
Kick date night (or day) up a notch by heading out to the back patio for your meal. Indian food is even better when plated, so make sure to bring out bowls and other dishes to enjoy your meal.
