Myself and a party of 4 had the 3 course set lunch here.
In many respects one couldnt complain-we were well received, staff were courteous, central table in a nicely furnished dining room, food well cooked and tasty.
However when thinking back although the waiting staff didn't do anything wrong there was no engagement with us, no attempt at conversation, apart from a standard query at the end of whether we were happy with the deserts.
One aspect that does cloud the experience came when we paid the bill- our pre lunch drink eg vodka and tonic came to with 10% service over £11 each.
Perhaps its this notion of country house style - if that's what you like and are happy to pay the high premium then yes come here. However if you want a similar level and quality of catering then there are just so many other venues nearby and in Brighton that are either better value or have more atmosphere albeit in a contemporary style. Regretfully unlikely to return here.
