It's a lovely restaurant in a lovely setting. Not been for about 5 years but I loved it. I treated the missus to dinner when she graduated and we stayed over in the manor as well. My favourite moment was actually sipping G&Ts in the garden on a lovely balmy evening.
There's a lot to be said for having a lovely meal, a few drinks in the bar, climbing up some stairs to bed to get up 8 hours later and go back down the stairs for a full English. Guardians were delivered to our breakfast table as well. Shame it was close season as a taxi to then take me to the AMEX would have been the perfect day.
Have you booked? If not probably think again. Tis good though. Assume you have done foragers, how about curry - azarro?or Sri lankan - moonstone.. better half is supposed to do good grub.. & makara too..
