A welcome addition to the Davisville/Mt Pleasant restaurant scene, even if it is just a few doors south of another good Thai joint, Thai Spicy House. The upside of that is both places are hotly competitive, with discounts and house specials aplenty.
My wife and I have been to The Friendly Thai several times, and have been impressed with the food on every occasion. The portions are plentiful and faithful to original recipes, while the service is attentive and pleasant, as the name of the road would indicate. Highly recommended.
