Good restaurant/pub food either Hyde Park or Primrose Hill

[coastalchick]

We are visiting London at weekend and OH fancies walking in parks. I've suggested Hyde Park or Primrose Hill (been to both before as lived in London though was 14 years ago!)

We'd like a nice lunch. Anyone have any recommendations, either on outskirts of Hyde Park or around Primrose Hill area?

PH -
L'Absinthe is good. Authentic French, good atmosphere, unpretentious.
Oka is apparently good, I haven't been myself.
Lemon is is still a stalwart. Good fun and quite good food.
Odettes but I haven't been for a while.

The engineer pub in PH is good too, and yes to Lemonia. L'absinthe is lovely too.
