In Thamel there are 2 great pasta houses that are nearly caddy corner to each other, Casa della Pasta & the La Doche Vita. When you get to the Khukuri knife corner in Thamel go down the narrow street right in front of it. When you get to the end of the street La Doche will be on the 2nd floor of the corner on your right & the Casa is just opposite.
Both resturants serve excellent Italian dishes, both with great atmosphere. I visited the Casa more but my time was shorter than I liked. They have good lassagna, spaghetti & other dishes. Both are highly recommended.
