Pizza Paja is a restaurant in the Phahon Yothin 11 alley near Ari in Bangkok that serves Italian-style pizza and pasta. The pizza is thin with crisp edges and comes with many topping choices, and the spaghetti is available in several versions. Food arrives relatively quickly, and because seating is limited it is better to reserve in advance. The restaurant is hard to find inside the alley and there is no place to park.
