We arrived just as breakfast was finishing and lunch was starting on a Sunday 12:00. We waited almost an hour for our starters and then another 40 mins before the main courses arrived. My minute chicken burger was so overcooked it was inedible - I sent it back . I was told it would be 6 mins for another burger but after 15 mins we gave up, paid and left.
Other diners arrived, ordered, ate and had left before we even had our starters. Shame as there were around 12-15 front of house staff who were trying hard but obviously the kitchen was understaffed and the weak link.
We won't be back what a waste of our Sunday midday.
