Excellent find

This place isn't much to look at from the outside but the food was absolutely amazing! My husband lived in Thailand and was very happy with the food. We will be back many times.

I was really looking forward to eating here, but the quality of the main dish was disappointing. Have tried Thai food in other, smaller towns and this was just not up to par.

I visit Sioux City several times a year and eat at Diamond Thai each time. I love Thai food and was so happy when this place opened some years back. It's a small, unassuming place, but the food is some of the best in the region, and a nice change from the burgers, steaks, and pizza that you usually find... More

Great Thai food and good service. Lots of options (the tom yum is my favorite), large portions, and reasonably priced. The food is flavorful but not too spicy. Also, they don't have a liquor license, but seemed to be cool with BYOB.

The food tastes authentic and delicious. The server didn't have much patience for my toddler but overall my visit wasn't bad. I'll definitely return.

We found Diamond Thai when searching where we should stop for lunch on our road trip. Fortunately, Diamond Thai already had a bit of a following. We were able to phone ahead and order what we wanted, well in advance of our arrival. Our timing was pushed, due to unexpected highway road construction and traffic - but we were pleasantly... More

The exterior is a little rough, and the interior is not glamorous. The food is wonderful. Reasonably priced for a generous portion. Try the spring rolls. One of my favorite places to eat in sioux city.
