Lovey food and setting, but the service was really quite poor sadly. Having booked a table for dinner and ordered our food, we were served a lovely starter and a great red wine. We then waited a long time for our mains, not a problem, or so we thought. Waiter apologised, not an issue for us, but as soon as our plates were cleared the manager said we had 15 minutes until we had to leave as someone else had book booked the table after us!! Desert was rushed, and the experience was really soured, and for an error not of our making but the kitchen/staff.
Overall, a lovely venue, good food at a good price but poor service that was a real disappointment for such an iconic brand.
