Nice list. Many things to try.
To add my own slight contribution:
The tofu banh mi at Clear Flour bakery is worth going out of your way for. Not out of the way as in booking a private jet from Hanoi to Boston, but worth veering off Harvard or Brighton or Brookline or Commonwealth or any nearby Ave. It’s well seasoned, with copious amounts of cilantro, not a token wisp – I’m glaring at you Bon Me – and nicely cut and proportioned cucumber, radish and carrot. Once or twice the tofu has been too-thick-sliced, but I quibble. Every bite is a perfect balance of crunch, spice and softness. The sesame baguette piece they use is perfect.
If you don’t eat it now don’t complain to me later that you’ve never lived.
OK, I’m on a sandwich rave. What else do I like so that you can decide if my judgments are sound. Off the top of what I fondly call my head, and in no particular order: roast beef at Flour (with horseradish and crisp shallots), the Hi-Riser breakfast sandwich at Hi-Rise (an elevated BEC), prosciutto-arugula on focaccia at La Saison (the bread makes the sandwich here), the Kent (turkey, bacon, roasted tomato, greens and sriracha) at Forge.
