Arguably a purveyor of one of the best sourdough loaves in London, Bartel’s, which has outlets in Sukhumvit and Sathorn, specializes in delightfully inventive sandwiches and toasties: think smoked salmon with sriracha or peanut butter and Nutella with banana, berries and granola. You can either take your sandwich to go or settle in for a cozy brunch. Pair your meal with one of the shakes and smoothies in pretty pastel colors, and make sure to leave with a cinnamon roll.
