I've had mixed experiences with the food here, but all in all it's a good place for Thai if you're in the area.
I love pad thai, but this pad thai is BAD. Not a very flavorful sauce, almost no veggies, and stale bits of tofu.
However, their yellow curry may be the best I've ever had. The cravings I get for that alone are enough to keep me going back there. The curry keeps very well- in fact, I think it may be even better when left in the fridge overnight.
The quality seems to vary greatly from dish to dish. Some are awesome, while some are really forgettable. Once you know what to get, though, Papaya Hut is worth checking out.
