If Chanpen seems like the only Thai restaurant in South Phoenix, it's probably because it is. But that's okay with owner and chef Chanpen Ramonaitis (whose Thai name is Tuk). She's happy to serve her expertly prepared classic Thai dishes and signature creations to anyone who happens upon her tiny, unassuming home. Along with street food eats like fried fish cakes and crispy Thai toast, there are colorful curries and stir-fried dishes laden with crunchy vegetables and, if you choose, pieces of slick and tender roasted duck. For more unique offerings and improvised dishes of Thai-style favorites, look to the specials board behind the counter.
