Between 3 and 4 stars for me. I got both take out here for a late lunch/early dinner and dined in for lunch once. Their take out coconut noodles were underwhelming, with pieces of cubed chicken that was a bit dry. I wonder if it was because I ordered take out at 3pm? But if it was based on that experience alone this would be closer to 2.5 stars. Size appears smaller on take out (this might be a container issue?).
However, their dine in service is quite good. My only qualm would be that they are fully booked for reservations. We tried to book day of, to be fair, but the system showed nothing available after 11:15am. So being the punctual people we are we showed up around 11:20 and were the only people in the restaurant until the 12pm rush - I swear I turned around and the entire restaurant was full! Though it was awkward at times, this did make for the best service, my water was never empty!
The khao soi I ordered was delicious and a large portion for lunch. Noodles were a good texture and I liked that they gave a side dish with additional garnishes so you could season it to your taste. Price is a bit high, which would prevent this place from becoming a regular lunch staple for me.
