Keep Sink where it is. Move Frig to place where the stove is, at present. Remove the "whatever it is" in the middle of the room and replace with a free standing island. In the freestanding island, install a cook top with an overhead hood (if there is nothing above the kitchen) or side blower in the cooktop. Make the island large enough that it can double as a breakfast bar.
The nice thing about this, you can keep cooking and you are looking out, either to children or guests.
