My husband and I will be arriving in Madrid on Sun. morning Dec. 11th. We know that dinner in Madrid is typically served late, and we are not really late night people to begin with. So we'd appreciate any recos for restaurants that serve dinner early. Proximity to our hotel-- the NH Nacional, Paseo del Prado 48-- would be a plus. This would be especially appreciated for Sun. since we are flying overnight from NYC, and will be totally exhausted.
