In East Lothian, Drift Cafe by Tantallon Castle is hipster and fancy, often busy, but with the best views in the world, I’m not surprised. Good coffee, cake and soup.
if lucky enough to get inside table, notice how they are carefully arranged so no table totally blocks the view for others.
also E Lothian, Glenkinchie Distillery is v pretty (thats why Diageo bought it, and I believe closed a better bit less-picturesque one), not been inside as on bike. Food truck outside tho!
