I head to The Food Train when they’re parked behind 101 Hartwell Ave in Lexington(bordering Bedford). Sweet Ginger panini was delish — rich in flavor, plenty of protein, and not greasy(yay!). Nice simple menu with something for meat-eaters and vegetarians. On Hartwell Ave, the truck is parked next to a small patio /garden area with a few tables with chairs – a nice quiet spot for a relaxing break from the workday.
