The review is based on eating in and take-out.
My first experience at Pai was when I had a take out of their Khao Soi with beef. Had to line up to pay for the food which is disappointing as you just have to watch your food get cold. When I opened the plastic container at home, I found extremely firm, wavy (very short wave length). It was simply very uncooked. The fried noodle was softer than the egg noodle once soaked in curry. The curry itself was creamy and nice but it would obviously would never stick to the hard noodle. I was extremely disappointed after reading such good reviews. So do not get takeout for noodles. Do not risk it.
However, when my friends came from the states, I decided to give this place another try. Ordered green curry and khao soi with beef. Green curry in coconut was really amazing. It was smooth and had such great depth of flavor rather than just being sweet as is from many thai restaurants. Khao soi turned out to be a completely different dish with the cooked noodle. The thick creamy oily curry was perfect for the egg noodles. It was really good with my leftover rice from green curry as well. Sangria was sangria.
So always eat in if you want noodles. Otherwise, you will be happy.
