This family run restaurant in the heart of Valparaiso was both welcoming and English speaking. I liked this place so much I visited it everyday while in the city. The menu was in several languages (Spanish, English and French).
The restaurant is located on the first storey of an old colonial house so it isn't the best access for wheelchairs etc.
The menu offered traditional western meals (lasagne, pizza etc) and had a vegetarian twist to Chilean dishes. Their homemade bread is also great (apparently most of the bread in Valparaiso is not vege friendly and made with lard). This is nowhere near fine dining but the welcoming nature made it a favourite of mine.
