Many years ago, during my visits to BA I used to have lunch at La Estancia.
There wasn't a special reason; just happened that I enjoyed hanging around Calle Florida and La Estancia was very good and near.

I've been reading all the posts (I've got to page 20) and haven't read any mention of this restaurant. Is it still good? Overpriced? Not worth the prices?
For lunch during weekdays, is it necessary to reserve, or should I just show up? I will be alone.

Thanks for any information.
