My goto topics for office chitchat are TV shows, video games, and sports in that order. Most people have at least some show they watch and will talk about, and others typically have a video game of some sort they play. Sports used to be first, but I've run into many people who have zero interest or knowledge in any sport personal or otherwise.
Topics I love to talk about but avoid, diet and exercise. Topics I avoid completely, politics.
Restaurants, bars, and events around town are a good topic as well. Travel is a good one too since many coworkers are either planning a vacation or were on one recently.
