The illusion would soon leave you when you hit the Diana Fountain, and the hordes of tourists. But if you wanted to maintain the Pride and Prejudice vibe you could do a lot worse than heading straight through the sunbathers, towards Kensington Palace's Orangery. This is a gem of a pit-spot: not all that more expensive than the park cafes, with nicer food and a beautiful setting. The boy, the husband and I enjoyed a delicious spring lunch on the terrace, overlooking the formal gardens and feeling very much as if we were at Downton Abbey. There is a decent children's menu, high chairs, and all the amenities (playgrounds, fountains, boating) of Hyde Park and Kensington Palace Gardens right by. We would highly recommend it!
I'm linking this up to Coombe Mill's fantastic Country Kids linky - thanks for having another interloping urban post!
