We went here on a Wednesday night and it was pretty busy so I thought that was a good sign off the bat. It's a super small space with tables almost on top of each other so if you're afraid of confined spaces and strangers, I would get takeout instead.
As for food, the Papaya Salad was some of the best I've ever had but the Basil Fried Rice was a little bland. The Massaman Curry with Shrimp tasted awesome except they left the tails on, which is a pet peeve of mine and made the dish quite annoying to eat.
Overall, the food was good and like most Thai food, tasted even better reheated the next day after the flavors set in. Service was decent too considering there was only one server for the whole place. I'd definitely hit up Ty Fun again if I were in the area.
