This might help: In Springfield, MA...Hartford CT area....Framingham, MA. Somewhere in Western MA I found actual homemade Oaxacan mole at some place. Waltham, MA has a couple good places too. I'm kind of lumping Salvadorian/Guatemalan in with Mexican here... Oh yeah. There's a truck in Springfield right off the interstate that's REALLY good. Good for anywhere and I've lived all over and grew up on this kind of food on the regular. Um, they make those birria tacos with Oxacan cheese where they griddle them like in Tijiuana. I haven't gotten those there yet. Look that up and you'll find them. Most places are very solid, but they still make me miss my favorite trucks and shacks in Mexico and across the US.

Springfield does have some super solid food options in general if you're into the whole $5 food made by a grandma in a shack thing rather than the VT $30 hyper local hipster thing. The $75 fried chicken in Winooski cracks me up. Someone took me there. It was fine, but I'd had better fried chicken in the south from gas stations for about 1/5 the price.
