HI Rosaly, Harper's is a very nice restaurant that offers a set Menu (
and also a la carte). This is a first class restaurant , choosing the
set Menu option you can have a very nice dinner or lunch for under $20.
This includes entree, main course, desert and wine and may be coffee I
am not sure of coffee.
There are a couple of Harper's Restaurants , I am thinking of the one
near the Hyatt hotel, there is another in the Recoleta area.
You might like to double check with your hotel about this information
since I am relying on my memory.
Buen viaje, Graziella.
