Since it is not actually serving the countertop and appears to be a reasonable distance from a sink, apparently this does not **need** to be GFCI protected. 

However, GFCI protection may still be a good idea, either at the receptacle (which I can see it is not), at the breaker or somewhere in between. While it is unlikely that you'll be reaching down to plug/unplug appliances while your hands are wet (which can easily happen at the real countertop receptacles), kitchens get wet, especially on the floor (at least in my house) so I think it would be a good idea.
