The foursquare Blog just announced that its geolocation service has forged a partnership with OpenTable, the online real-time restaurant reservation platform. Essentially, foursquare users can access its Explore recommendation engine to research the restaurants of a specific locality, and then go on to book reservations with the new OpenTable integration. Below is a screen of the new interface:

Foursquare users can now make one-click reservations at over 25,000 major city restaurants in the U.S., and OpenTable is expanding. It’s as easy as clicking ‘make a reservation.’

The San Francisco-based OpenTable was founded in 1998, and has since seated 280 million diners worldwide. The service is available in the U.S., Canada, Germany, Japan, Mexico, and the United Kingdom. In February, the company announced the winners of the 2012 Diner’s Choice Award, listing the top 100 restaurants in the U.S.

In related news, today foursquare announced that its users can now instantly verify their businesses for a small fee, instead of having to wait up to a month to register via snail mail.
