Time Out says
Co-incidence Process Coffee, the small kiosk on Soi Sukhumvit 49 has been expanded into a full-fledged café and lifestyle shop that sells Co-incidence-branded merchandise, from stationery items to toiletries. After browsing the store, indulge in a number of comfort bites, such as the Cheese and BBQ Sauce Hot Dog or the Bacon and Cream Spinach Sandwich.
The coffee here, which uses Arabica beans from Nan mixed with beans from Chiang Rai, is a medium roast with a faintly fruity and nutty taste. We recommended the Black Tonic, a
strong, long shot black coffee with tonic water and sliced lemon. Have it with their carrot cake.
