Oh hmmm, no. I don't get over that part of the state very often these days (used to work down at the Bay Campus in 'Gansett/Saunderstown). Technically that's North Kingston. Kingston proper (and not South Kingstown - note speeling difference) is much closer to me (southwest corner of the state). Of course this is all at Rhode Island scale

. These days I'm going west into CT most of the time, opposite of the before-times.
No surprise that was your experience in '86.
I grew up in CT and lived out in Santa Fe in '97-'98 and finally learned what southwestern food was all about. No wonder I didn't like it growing up. It wasn't until ~2004 that you could reliably get decent "Mexican" food even in NYC, where I lived for some time after Santa Fe.
There's a little Mexican market in Willamantic, CT of all nowheresville places. It has a tiny restaurant attached, and the young dude cooking there blew my mind. That was a bunch of years ago. And up in Providence there's a Mexican/Salvadoran joint called Hacienda (west side - there might be two places with the same name?) that has great, cheap, authentic grub. They do pupusas, grind their own corn for sweet corn tamales, and make their own horchata. The little carnitas tacos are amazeballs too. Mmmm.... Not far from the SteelYard, Revival Brewing (new loc), and a bunch of other stuff.
