I went here for lunch today and there wasn't any lineup at all. The khao soi was delicious. Large chunks of tender beef and super crispy egg noodles is the best combination ever invented. My boyfriend got the yellow curry of the day and it was good too. I didn't find the yellow curry to be spectacular or anything since they usually pre make the lunch specials in advance. So the curry was comparable to salad king.
The waitress was friendly as well. The only thing I could suggest is for them to increase the rice size. Since it cost $3 for additional bowls of rice and there was a lot of curry sauce left. Also, I ordered spicy (level 3) and it wasn't spicy at all. So I would suggest thai spicy or higher if you are looking for szaichuan food spicy.
