Pam's, on 49th Street between 9th and 10th avenue. Pam, the chief, often comes out of the kitchen to see how things are. Can get very, very spicy. I've been there three times. Very good red and green curries. Excellent fried fish and chicken satay. Decent dumplings. Very, very spiecy but good shrimp with string beans and red curry. Best Thai I've had in NYC.
