We were recently in Jackson, WY and had two great meals. The first was at Sanchez Mexican Food at the corner of Glenwood and Pearl. Very small with outside seating. We had carnitas tacos with hot green salsa, onion and cilantro, and carnitas tacos with chipotle sauce. All of the salsas were very distinctive and really, really good! With chips,salsa and drinks, lunch came to about $14.
The second meal was breakfast at a healthy foods store called Natural Foods. They have a cafe in the back. Service is kind of slow, but we had wonderful huevos rancheros, blueberry pancakes, fruit salad, and scrambled eggs.
