Those in need of a refreshment stop will be pleased to know there's a cafe right in the middle of Parque Nacional Manuel Antonio selling cold drinks, ice creams, coffee, snacks (pizzas, pastries, sandwiches) and souvenirs. There's also mask and snorkel rental here (US$13 per day), plus showers, changing facilities and restrooms. It's located before the turnoff to Playa Gemelas.
