Koji is a great sushi spot about 20 minutes north of Santa Teresa. The sushi is authentic and delicious (due to the fresh fish they catch that day). If you don't make a reservation you wont get in, and even if you do you probably will have to wait for a table. Don't be surprised if your dinner takes 5 hours. Try to breath in and enjoy the candle lit patio under the tropical trees. If you are from NYC or haven't had time to adjust to Costa Rica time, skip this place. You will be too annoyed by the service to enjoy the delicious meal. The sushi is inventive and oh so good. The menu doesn't change as much as you'd think, but it doesn't have to. We stayed in Santa Teresa for a month and came here every week.
