H2O Java Shop is a coffee house that adjoins the H2O cafe restaurant. Its a pretty nice place, with a few high top tables and club chairs inside and a small oceanfront patio with tables outside. They sell the expect mix of espresso and coffee drinks and the prices are ok ($3.50 for a medium latte).
They also have food; fresh fruit, cakes and cookies.
Its the best place to get coffee in the area.
