The menu is extensive. There are currently two specials of the day... one for 7 soles and the other for 9 soles.
I first went here in June 2014 and found it average. I went back again in November 2014 (it's open Sunday), and won't go back. The mixed salad was passable, but the main plate pathetic. 3 different starches on the plate (rice, potatoes, plantain), and no protein to be found. Nothing green, and overall not appetizing at all.
There are two better restaurants over on Jiron Carabaya that had better food for roughly the same price.
It's open 7 days a week. There are two other veggie restaurants on the same block (at 399 and 337), so plenty to choose from if you're in this area. I have not tried the other two, but the staff at 399 was unfriendly, so I didn't eat there.
