Arran has a number of hotels that do food. Lagg Hotel, although quite a distance from Ferghan Mhor, is a beautiful old hotel that is worth visiting. They always have vegan food options for lunch or dinner (need to book). Right next door is also Cafe Velo where you can get some vegan baking. The three bean chilli from 2019 is pictured below. We went to stay at Lagg Hotel 2021 and had some great food for dinner. Also pictured.
