I intensely dislike kitchen/diners! I don't want to sit down to eat in the room where the meal was cooked.
We have, and use, a separate dining room, with most of our meals being eaten in there, even though it's usually just the two of us.
There are two armchairs in there too, and my late DF's desk is in the corner, alongside a very lovely Walnut Chiffonier, which was one of our first 'good' antiques.
The dining table is a circular tilt top, but it's never tilted. It's also Walnut, and beautiful, so is only covered with a cloth at mealtimes.
We eat outside when the weather's suitable, yesterday evening was glorious, the patio nearest to the house had been in shade for a couple of hours and was wonderfully cool, we sat out there for ages enjoying the coolness.
We're having an Orangery built in a couple of months, just waiting on the builders, so we'll probably eat in there a lot in future.
