Delicious sandwiches and pastries, but Mariposa's pretzel rolls are the best thing on the menu. :)
Flour Bakery Cafe
190 Massachusetts Ave
The best coffee and bakery I've found yet in Cambridge. Their sticky bun beat Bobby Flay in a Food Network Throwdown. Sandwiches (especially BLT), macaroons, & scones, also terrific. Delicious stuff!
