I have visited Harbour House 5 times in the last few months which says all you need to know. The food is delicious - I particularly loved the tuna nicoise over summer, and now the surf and turf is beautiful. I am coeliac and the gluten free options are delicious, and this has been handled professionally and with absolutely no issues.
It is a lovely venue both inside and on the terrace. The thing that has really stood out is the service - the waiting staff are awesome, friendly and attentive. I recommended it to my colleague and we are now coming to Harbour House for our work Christmas party as well!
