Nashoba Brook Cafe, located far from the historic downtown, is on a side
street and surprisingly hard to find.  We had to call for directions. 
Even though we were less than two blocks away when we called, I'm glad
Di Yin put them on speakerphone because the directions were so
convoluted that if I hadn't heard them myself, I wouldn't have believed
them: "past the auto dealership ... cross the parking lot by the gas
station ... down a brick alley ... we don't really have a sign."  Can
you even spot the entrance in this picture?
