This is indeed what you would call a good restaurant. The environment is very friendly and relaxed, the food is of great quality and you can tell the staff puts their hearts into their jobs. They even have a small corner reserved to selling a good variety of vegan goodies (cheese, sausages, frozen meals, snacks) for actual cheap prices - however, I'll have to disagree both with the classification of "inexpensive" this place holds and the generous portion sizes it was claimed to have which are quite relative concepts anyway (the majority of restaurants in Granada are quite expensive, yes, but that doesn't make Hicuri cheap and I like to feel full after a meal, which resulted in me feeling compelled to buy an entrée and a dessert).
Many people make reservations in advance and the place is busy (when I went there about 4 tables were being prepared) so perhaps try and come a bit before regular Spanish eating hours.
Cons: portion sizes, more expensive than expected
