We almost turned around and left because the floor was littered with leaves and other debris from diners. The table we were seated at had crusted on food/cheese/salsa that could not easily be wiped clean with a cloth. It was stuck on and the utensils had spots on them too.
The meals we had were just fine, enchilladas and chile rellenos were tasty and servings huge. Service was friendly and very efficient. Prices were about average for Santa Fe.
There are so many restaurant choices in Santa Fe, we will not be returning to Blue Corn because of the cleanliness issue.
