Recommendations - DH and I have a week in Cambridgeshire

[Peatot]

Based in Cambridge itself. We like walking, history, eating/pubs, wildlife, gardens.

What's special? What shouldn't we miss? I'm a bit gutted King's College Chapel doesn't start their services again until term restarts

I really like the Cambridge Brew house pub on King st.
They brew their own beer and make fab fish finger sandwiches, They also have a good mix of people in there.
Aromi and Savino's do lovely Italian coffee. Much nicer than the chain places.
Loads of places do burgers if you like them.
