We stumbled upon La Bombonera in San Francisco Street with about forty-five minutes before we had to leave for our flight and we were looking desperately for something to eat. The place has been in operation since 1902 and apparently it's in all the tourist books as an "authentic" place where locals eat. We had no idea. It was a great place to enjoy our last meal in Puerto Rico (miraculously nothing was FRIED).
The most awesome thing about this place: the 1898 coffee machine, originally built in Havana, in which they brew their own brand of coffee.
