If you're heading out to eat without a pre-booked reservation—and wondering whether there's already a long wait at your favorite restaurant—now you won't have to call ahead. In its latest update, Google Maps will show you exactly how busy restaurants are—in real time.
For a while, now, Google Maps has featured "Popular Times" in restaurant listings. "Popular times are based on average popularity over the last several weeks," the search engine FAQ explains—and it's predictive, not live. "Popularity for any given hour is shown relative to the typical peak popularity for the business for the week."
As of the iOS app's most recent update, today, Google Maps will showcase live visit data, which is updated in real time. There's also a new feature that show the average amount of time customers spend in the restaurant.
