The food here is delicious, and prices very reasonable. Atmosphere and service are both excellent. Try the masamam beef and barbecue lamb. owners are a lovely, hardworking family who have been open at the same location for almost 20 years( maybe longer)

We passed by this place all the time for years but out of the blue we finally decided to try it. What a pleasant surprise! It's a small place, but clean and well appointed. Seemed authentic enough. Food was also authentic enough, besides being tasty....More

Long list of Thai favorites. Make that a very long list.. Shrimp rolls were ok, but the sauce was great. Yellow chicken curry was fantastic. Pad Thai - not bad but not memorable. Wine seleciton is very basic.

We thoroughly enjoyed our meal last night....there were so many Thai restaurants to choose from in Palo Alto and I am glad I chose this one. The menu was extensive. The food was tasty. The waiter was kind and warm. It took a little longer...More
