6:00 pm - 9:00 pm
Dress is dinner casual. The weather will be warm and humid, dress accordingly.
I am realizing that locations/addresses are not typical for Costa Rica. The restaurant lists their location as: Corona Street 150 meters behind Hotel Pasatiempo Guanacaste Tamarindo, 50309, Costa Rica Most in CR use Waze for their maps app to get around, for GPS. This is recommended.
5:00 pm
Casual Attire: Anything goes, from sundresses and sandals to jeans and tees.
Casual beach attire is recommended as the weather will likely be warm. Rain is a possibility as always for this area. Plan accordingly.
