I am not a big sushi person, but my husband was really excited to try this place out so he made reservations. I would definitely recommend reservations, this place was very busy seeing as how it is in a pretty remote location. We had to arrange a taxi from our hotel and it was nighttime, the roads were dark and potholed and then out of nowhere Koji's. I ended up enjoying the sushi, though I do not think I appreciated it like a sushi fan would. If the service was a little faster we would have gotten dessert, but we were a bit crunched for time since we needed to meet our taxi. This place just felt so out of nowhere and the atmosphere was so interesting and different than any place we went to in Costa Rica. I am really glad we ate dinner there.
