[Went there 2 times in late December 2014 / The address is: calle Zepita 704, at the corner with Junín / The set menu is at 5 soles / the hours they told me were: Monday-Saturday 8h30-16h30, Sunday 8h30-16h]
I went there because the other restaurant Sabor Supremo (or Suprema Sazón as it seems to be the new name) wasn't able to serve us. The set menu (S/. 5) includes a small starter, a soup, a main course and a drink. The food was okay, but not flavourful and the place was very dark (if you don't seat near the door you won't receive daylight) and kind of messy (too many tables and chairs for the space available.
Wasn't my best experience, but okay.
Cons: Dark and messy, Staff unfriendly
