Enjoy a meal in good company by forcing everyone to relinquish their phones! Invite them to charge their phones (Who's going to say no to that?) So you can really focus on hanging out instead of checking work email, social media, selfies, or googling a random fact to prove a point in your discussion on narwhals.
Still need things to talk about? Have a listen to The Dinner Party Podcast, which has an assortment of relevant pop culture sound bites, jokes, cocktail recipes and stories to chat about. And while your at it, don't forget to bring a bottle of wine! See this write-up in case your not sure what wine will pair with dinner, by the Kitchn.
Cheers!
