Noodlehead is definitely one of my favorite Shadyside restaurants. They have a small menu, but don't let that deter you. Everything is deliciousssss. Pad Thai is a classic and absolutely wonderful. I recommend the See Yew.
You can order spicy levels 1-5. I personally order a 4 or 5 each time because I love spicy food. My friends who have ordered a 1 said it has a very slight bite but very manageable for those who don't like the hot stuff.
The atmosphere is wonderful, and I love the decor.
Don't forget, they are BYOB! And it's only a 50-cent/person recycling fee.
Just keep in mind, they have no phone, don't take reservations, and are cash only. Take out is available, but you have to order in person. Highly recommend!!
