If you want good thai food without the lineup of Pai, then Sukho Thai is your best bet!
I came here with my girlfriend on a Friday evening and we barely had to wait at peak dinner time. I was told that their food is comparable to Pai but if you're incredibly hungry and craving good thai food, waiting is the last thing you'd want to do. There comes a point where a minimal upgrade in quality of food doesn't necessitate the wait.
We ordered the pad kee mao and the khao soi which are the classics here and they did not disappoint. The khao soi was flavorful, rich, and very creamy. The beef here is meaty with a nice chew, they are the chunky kind but not too tough. The pad kee mao was tasty although I'm not sure if it was peppery and herby (basil) enough as the flavor profile indicates - there was a lack of bell peppers. We also had the fried shrimp appetizer which was nice a crispy straight out from the fryer but I'm not sure if I'd order it again. I'd really recommend the thai iced tea which is a straightup flavor punch, you can taste the intenseness of the tea and creaminess from the condensed milk. Portion sizes were sizable and we were stuffed by the end of the meal.
The restaurant is very simple with a bar area yet also a bit rustic with an entire brick wall on one side. Service was acceptable and was fairly quick and efficient.
