Do you like to frequent places when they're at their busiest or do you prefer to slip in when no one else is around? No matter. Google Search will now help you do both. When you search for certain establishments, Google will show you which times of the day are the most popular.
Just search for a place's name and click on its card in the search results. Underneath the address and phone number you might see a scrollable chart showing when folks tend to stop by.
Results will vary. I had success when trying Blue Bottle Williamsburg, the coffee shop in Google's example. I didn't get results for the nearest board game shop in my area, but I had good luck with the local Barnes & Noble.
If you don't want to search before going, here's the gist. Go on a Tuesday while everyone is at work. Just don't all do it at once.
