My trip to Edinburgh last October coincided with the vegan night, and I'm so glad it did! It's a really fancy setting, and they don't rough it when it's vegan night, they still go for impressive fancy food. The staff were so lovely and attentive, and made some good recommendations on the dishes too. There were three choices for every course, and they were all very tempting. The desserts were the real highlight, in particular a chocolate tart that was just sublime.
