Our Story
A Decade of Real Thai Flavor
Diho Siam began with a simple promise: honest Thai and Chinese cooking, made fresh every day. For more than ten years our kitchens across Southern Orange County have hand-crafted the dishes our neighbors crave - pan-fried Pad Thai, fragrant yellow curry simmered in coconut milk, and crisp orange peel chicken. Every plate leaves our woks hot, bright, and packed with the bold spice our regulars come back for again and again.

This is our first experience with Diho and we will be regulars... & we're really picky about our Thai Food. The beef Satay was tender & juicy. The yellow curry pork had a beautiful blend of vibrant seasoning. The beef Laab was fresh & delicious . The cream cheese wontons were a huge portion of crisp appetizers for sharing all around. The whole meal was just great. Everyone was very pleased.

My favorite Thai place ever!!! They always accommodate my vegan diet with the Pad Thai and it's still tasty and delicious every time. My partner also loves the Glass Noodles with the seafood mix and both dishes are always hot and fresh. That's why I've been a regular customer for over a year now and definitely plan and ordering from here for the foreseeable future :)

Some of the best Thai food in the area for a price that also beats out all the other local Thai restaurants. I've ordered Pad Thai from most of the spots in the Aliso and Mission Viejo area and the Pad Thai (One of Thailand's Best Known Noodle Dishes) from here is at the top of my list. They really get it right. The same goes for the Tom Kha (Thai Hot & Sour Coconut Soup) (Chicken) which is one of the best out of the bunch as well. They properly strain out the aromatics leaving a delicious savory soup that you can finish to the last drop. Highly recommended!
