This week we say goodbye to Bambū Café, which is closing its doors after a three-year run on Rockville Pike. The Vietnamese-inspired chain, which specialized in sweet coffees and bean-based chè drinks, faced tough competition in an area that’s home to more than a dozen bubble tea shops. (Editor’s note: Bambu was dark and appeared to have already closed when we stopped by earlier this week, but it has since reopened and management says its final day will be Oct. 31st.) If you’re looking for another place to try, the Tropical Smoothie Cafe just opened a few blocks away. More on that in our Sept. 22nd edition.
