After a delicious dinner of the Peruvian sea bass, my husband and I were overcharged $12 at this restaurant. We caught it after we paid. The cashier was not surprised, and refunded our money from his own wallet! It appeared to us that the staff was overcharging and keeping the difference between the bill and the actual charge. Unfortunately, I have been overcharged many times in Costa Rica. Locals tell me that Americans are often overcharged, so always review your check carefully.
