This place is simple and the staff is friendly. I was staying downtown on business and went here numerous times. The Pad Thai (spicy) was delicious. The person I traveled with had Drunken Noodles which she loved. Flavors here are great and the food was fresh. For appetizers we had the spring rolls (my favorite), veggie rolls, and the sweet potato appetizer. All three were very good- but I highly recommend the Spring rolls. These were fresh and light and the sauces were creative and both delicious.
The place was clean and comfortable. It wasn't loud and the tables were situated to offer some privacy which was nice for good conversation.
I would recommend Thai'd Up to anyone looking for good Thai good in downtown Phoenix!
