do you live alone do you often entertain people at your house?if you have a family or looking to start a family or have family over I would go kitchen island with bar stools up to it on one side. if you enjoy the space that you have right now and don't often have many people over then having a table you can push to the side would also be a very good option.

It looks like this is your only dining space? If so, I would absolutely do a table. While I love our island I wouldn’t want it as our only eating space. I also think that it would hurt resale to have no where for a table. You could however do an island that has a lower table portion attached, if you have the space.
