café RST is a neighborhood café and small-batch roastery on the first floor of the Mukaeru complex overlooking Kesennuma Port. They roast single-farm beans on site and serve drip coffee alongside simple dishes using local seafood and dairy.
Open since 2018, the café emphasizes Kesennuma-sourced ingredients (including Morland milk soft-serve) and lists hours as 10:00–20:00 with last orders at 19:30; closures are irregular.
