    Hi, We've recently built our meta search engine and currently building our own ads platform from scratch. One thing we feel that is missing is a google style places addition which we realize BING has now. We've added a screenshot as an example of what we are looking to achieve. We use a bing api as part of our meta platform so we will most likely need to integrate that with our search. Our Search results take about 1 second to return so it will need to be fast and you can see from our screenshot we have placed a red line over the elements we want removed as we want to keep users on our website and not send them to bing.
