Is that tiny fridge going to be your only one, or are you going to have another one, elsewhere?
Also make sure that hob is an induction hob, rather than saving a couple of quid (because the difference in price is small, these days) on a halogen hob. It's just much safer if people are going to be sitting near it at the breakfast bar. If you have young kids, I would re-think having that as a seating area, completely. You have plenty of space for a table in there.
