We were only in one-star restaurants—Scorrybreac the first night, Three Chimneys the second night, on the Isle of Skye. (It didn't help that we had just seen The Menu, as well. )
Scorybreac didn't miss a beat, service was like clockwork, and they told a story about the all-local ingredients that made each dish. A 3+ hour experience that went by too fast.
At Three Chimneys, the food was good but less memorable, and the service very uneven. Dinner felt long. (Sorry, no pics.)
