When people ask me what restaurant is a MUST in Pittsburgh when they visit, I always recommend Noodlehead. It's been one of my favorite Thai restaurants since my freshman year. And it's pretty easy to get to by riding a 71B.
The interior is pretty hip and the servers are always very welcoming. My go-to is usually the Pad See Yew or the Pad Kee Mao with spice level 3. I don't really know how well to describe their food because it's just that good. Not too greasy or sweet. Their pork belly steamed buns are a delicious addition as well! One order comes with two so it's perfect to share with another person. Another recent favorite has become the Street Noodle #1 dish. My first experience with it was that it was too sweet for my taste but I kept giving it another try and it's become another one of my go-to's. The Thai chicken that comes with that dish is tender on the inside and crispy on the outside.
The only downside may be that it's cash only here but that doesn't stop me from coming :)
Also! After dining here, most people head over next door to Millie's Homemade Icecream. But that's for another review
