Reserve a table under the large oak that is central to Nemo’s patio. Breathe in the aromatic tropical breezes that drift in off the ocean. Or grab a stool inside at the kitchen bar, where patrons are invited cohort with the cooks. Sample from a meticulously selected smattering of boutique American vintages. And don’t skip pastry chef Hedy Goldsmith’s renowned sweet finales. Try anything chocolate.
