Thanks to my pal for being thoughtful and ordering me my very own individual buffet box from https://davids-kitchen.co.uk in Kirkcaldy who catered for her hubby's birthday party - all of it was delicious!
Sandwiches (ham+coleslaw and egg mayo), sausage roll, scone with butter+jam and a slice of lemon drizzle cake.
Came in it's own sealed container and marked gluten free - all other platters were also in sealed containers.
No separate GF menu but website does state "Our menus are flexible and items can be changed upon request. We can also alter the selection to suit vegetarian and celiac diets"
