It was one of my favorites. The restaurant part however was only in the last years. Before that it was a traditional confiteria. Waiters were professional, as you say, just as they are (were) in La Biela. I wonder what happened to all the beautiful furniture in the Richmond. By the way, the Richmond is mentioned in Graham Greene's novel The Honourary Consul, set in Argentina.IMHO, Florida's Confiteria Richmond was the best. Great food, classy decor, career waiters, comfortable armchairs, good lighting, no music. The perfect place to go with friends, or a book, and spend three hours enjoying the experience.
Sadly, it closed its doors in 2011, and was turned into a cheap-looking sports equipment store. More's the pity.
