I am visiting Spain for the first time in more than a decade, this time bringing my wife. In Madrid for 3 nights, and one of those nights I think should be a "tapas" tour. Is it best to stick to Huertas area, we are staying, or are there recommended places/tours? I have read about La Dolores and La Plateria. Also, what are best resto recmmdations in Huertas/Santa Ana, or is it best to head to Chueca for sit down dinners?
