I understand that by doing --- query.near('_geoloc', coord, 10); gives me all restaurants ordered by distance within 10 miles. But what is that distance value? is there any way to get it?

This is not returned as part of the query. However, given that you have `coord`, and the returned restaurants will have a `_geoloc` field, you can use the [Haversine formula](http://www.movable-type.co.uk/scripts/latlong.html) to calculate the distance yourself.
