Carpe Diem
Homemade pasta (l,d; $$)
The best homemade pasta in Cusco is at Carpe Diem. They also have good pizzas and great desserts.
If you want something sweet, try to tiramisu made at your table. The server will bring homemade mascarpone, ladyfinger-like cakes, espresso and cinnamon to the table and make you a very traditional and excellent tiramisu. Service is good.
