Mushroom Deluxe

Hongos Deluxe · app pricing (colones)

Mushrooms, crispy onion, aioli and emmental on a sweet bun with a beef patty, 882 kcal, which is the biggest number the Costa Rican site publishes for a burger. The current US board has no mushroom burger, and a crispy chicken version of this one runs beside it.
