Cielito Lindo in Brookings? Used to be an old gas station (many years ago).@Aruka I had one of the best burritos in my life at this little convenience store/shop in some tiny coastal southern Oregon town while driving through. Guy smoked killer meats, made his hot sauces, etc. May be too far from you, but daaaaamn!!
I've yet to try it, but don't get down there during lunch/dinner times too often (once or twice a month)
Many locals rave about it. Looks fairly authentic, hole in the wallish, and seems to be above par.
Most Mex places here use too much rice, beans, lettuce inside burritos.
I personally judge a Mex food place by their chile rellenos or chile verde. If those are good/authentic, the rest is usually pretty good too.
