Foursquare’s users can now order delivery through the geolocation check-in app. The order delivery is supported through GrubHub Seamless. This means that users can now order delivery from thousands of restaurants. If a participating restaurant supports the order delivery, a GrubHub or Seamless icon will be displayed at the bottom of the Foursquare app. You can also filter results specifically for GrubHub Seamless by adding the word “delivery” to the end of the search of a restaurant. GrubHub and Seamless merged this past August.
