As a local let me tell you that this restaurant is one of the less know gems in the city. The location is pretty central but there isn´t many things to do arround. They just did a renovation but I didn´t like it very much.
Now to the good stuff, the food. I recomend going for breakfast (sundays are closed) for starters try a cup of hot chocolate with a selection recent made bakery. And for main course you can´t go wrong everything is great. They also make some great combinations of fresh juices, try de "mandarina juice" but is seasonal during the end of the year.
And for the quality of the food it is a great deal just go and try it!!!
