Americans will be glad to find a place where they can dine at something close to the supper hour they’re used to in this atmospheric restaurant on a small street in the Gothic Quarter. The high-ceilinged stone room creates just the right environment for a romantic dinner, with service that’s friendly but unobtrusive. Dishes are beautifully presented, most of them twists on traditional Catalan themes, like a tender sea bass in a tomato sauce and calamares a la plancha beautifully rolled into cylinders and served on a bed of white beans. Save room for dessert; there’s an interesting twist on the classic tarte tatin.
