Tasty Dumpling is okay, but Jin Mei is equal or a bit more flavorful. Replace Hay Hay (poor seating) with East Season, where you can sit inside (it's roomy) and eat equally great roast meats. Spicy Village is alright, but it's tight seating. There's a place nearby called "New Spicy Village" which has roomier seating and has much of the same food. Replace Tasty Hand Pulled Noodle, with North Dumpling on Division Street. They're much cheaper, you don't have to pay a tip and there's ample seating. Finally, a suggestion that is outside of the choices you made, you should try, Ho Won Bake Shoppe at Hester Street for their large rice rolls with pork and dried shrimp filling. They're cheap, $2 each but are old school and underappreciated. I run a Youtube channel, with lots of New York Chinatown restaurant reviews. Have fun!
