Thanks to bare concrete walls and liberal use of copper and blacks, CPS Coffee feels very in-the-moment. The baristas at this menswear store-turned-cafe counter specialize in slow-brew coffee and tea blends left to infuse for up to 16 hours—think flavor-packed combinations like the Chai Rose & White Tea Lemonade (B150) or, our favorite, the Green Tea Beehive (B150). There’s also a respectable selection of croissants (B110-150) to tide you over until lunch. Two further branches are in the works, at Terminal 21 and IconSiam.
