"The next time your plan to spend as little time as possible in Back Bay Station backfires, resulting in you missing your train, console yourself at Cha Cha Cha. The tacos and burritos sold at this cart in the lobby are not only affordable, but they’re seriously flavorful with really tender meat. We’ve heard stories that, if you’re crying, they’ll give you a taco for free, too - but maybe don’t risk upsetting your emotional balance just to save $2.85." - Dan Secatore
