Yelp's US restaurant booking service managed 5.6m diners in Valentine's week 2019

""Yelp Inc. (NYSE:YELP), the company that connects people with great local businesses, today announced strong growth and momentum in its restaurant services offerings, with a record-setting Valentine's Day week in which Yelp’s reservation and waitlist software handled 5.6 million diners. This comes on the heels of the company closing out 2018 by managing 22 million diners in December, driven in part by rapid growth in diners booking directly through the Yelp app, which tripled year over year in the fourth quarter compared to Q4 2017."

Note - this is number of diners, not number of bookings; a table for four is four, not one.  Still, big numbers!
