The best thai place around. I'm a big thai food guy and have tried all the local places around, this one is by far the best in my opinion. Great food. Great atmosphere. Great service. THE DRUNKEN NOODLE IS AMAZING 🍜

Siam Pepper is the best around, hands down! They have their Pad See Ew down to the science! I’ve tried Pad See Ew in many other places and none have come remotely good as Siam Pepper. When you lunch in during lunch hours the soup they give you on the house is so tastes! The dumplings, just as good. They’ve Pad Tai is another dish that’s spot on.
Although this place is by my job. On some days off I drive 40 mins give or take just to eat here. Highly recommended...

I was recently here with my husband for a spontaneous dinner out. (I frequent this place often for take out). The flavors are exceptional! Every dish, whether dine or take out, that I’ve ordered from here is savory and the right amount of sweetness! It’s like eating my mom’s food at a restaurant- authentic and tasty! Highly recommend. Service is a little bland- not a whole lot interactions. But if you don’t care for that, this is an awesome place for genuine Thai...
