Visit Scotland, the official Tourist Authority of Scotland, has created a great interactive guide to finding a great place to have a cup of tea in Scotland.
Now, when traveling, you can enter your location and select a few critieria and you will be presented with a list of local cafes. Then, you can find a nice local Scottish cafe to have a cup of your favorite Brodies Tea. Bookmark the site on your mobile device. Just go to the cafe days section of VisitScotland.com.
