La Briciola is no where near Plaza Espana...it is on the corner of Merino and Padre Billini and because of the traffic that is now going through and destroying Plaz Espana it is by far the best choice of the three...it is a very good semi formal restaurant with a great atmosphere . Yes there are places you can park ,,there is the public car park on Jose Reyes just below Conde and the parking on the Calle Arzbisipo Noel is safe ..you will need to tip the guys 50 pesos or so.. but they have sharp eyes . Both these places are less than 5 minutes walk from la Briciola
