There're a tonne of places for lunch in Karen but this is head-and-shoulders the best. Really fresh ingredients, great menu (recommend mushroom quiche) including super salads, surprising juices (avocado and pineapple, anyone?!). There's a lovely feel of being on the terrace of a friend's house, just a friend who happens to be the best chef of anyone you know.
I gather there's super wifi, but I didn't try it. Instead plans for a quick sandwich with a friend turned into two hours of lazy chat and a proper lunch. Highly recommended - in fact, I'd say even if you're not in Karen, make a detour to go for lunch here. Super stuff, thanks to all.
