Casa Cavia is a gorgeous restaurant & concept store situated in a lovely renovated Belle Époque mansion. Chef Julieta Caruso serves inventive unusual Argentine dishes, ideal for a fun brunch or afternoon tea (with one of their yummy homemade dulce de leche stuffed baked goods). If you go for drinks, experiment any of their superb cocktails in the beautiful garden. Be aware: this is one of the toughest reservations in the city.
