This bakery and restaurant is consistently busy, and with good reason. Right in the middle of the main strip in Jaco it is easily accessible from all parts of town, and it well worth it. Churros are a staple, but if you want to step away from the sugar, there is a multitude of other treats available from both Costa Rican and American cuisine. There is also a patio upstairs overlooking the main street.
I have started many a day trip to manuel antonio at Pachi's Pan. The bus stop is right out front, so why not grab a coffee and a few empanadas to begin your excursion.
