This little hole in the wall has incredible food! I had their Thai iced tea and green rotee, which were both delicious. It's inexpensive and has nice decor. One thing to note is that it is small and busy. Make sure to add yourself to the waitlist, which is on the wall to the left of the door when you enter. They even do a neat little decoration with the straw wrapper when you get the drink, as pictured
The best Thai food I've ever eaten, and possibly the best restaurant I've been to in the entirety of San Francisco. Small but cozy space that fills up fast, but not to be missed. Closed on Mondays.
