I stumbled upon Let´s Go Bananas by pure occasion, mostly because the menu has a breakfast for 6 Soles (every other restaurant in the area - for 10). The atmosphere is quite nice, there´s wifi, but my favorites are the lunch combos. For 10 Soles you can get a very tasty veggie soup and a sandwich, which will totally fill you up. I never had to wait more than 4-5 minutes to get the meal served. As for coffee, it´s pretty good considering that guys do not have a coffee machine (understandably, as those are insanely expensive). Try regular coffee with milk, and you won´t be disappointed! The serving is quite generous, too. All in all, a recommended place for reliable tasty and safe-to-eat food, especially if you are vegetarian tired of white rice and beans.
Oh and there´s a hostel just behind the café, 10 Soles per night in the moment of writing.
