The cluster of wonderful European eateries on Belden Place includes this spare, modern Spanish restaurant, which draws locals with its menu of Catalan tapas and paellas. The open kitchen sends out small plates such as white anchovies with pears and Idiazábal cheese, sherry-scented fish cheeks, warm octopus with tiny potatoes, and blood sausage with white beans. The paellas, each serving presented in an iron skillet, bring together inviting combinations such as chicken, rabbit, and mushrooms.
