Being a vegetarian I thought I would be head over heels for Diamond Thai. If you are into quirky the ambiance is great, and the owners are really friendly! I've eaten here a couple of times and am not blown away by the food. I would love to see more dedicated vegetarian options and a little more variety on flavors.... More

I have lived in Sioux City Area for over 3 years and was excited to find some ethnic food other than Mexican restaurants when I heard about Diamond Thai, I have had much much better Thai food, but this was good and I have and will go back. Not everything on the menu is available, including my favorite soup, probably... More

This is a must-stop restaurant for us when we're in Sioux City. Food is always top-notch. This time, we had a Thai food virgin with us. He ordered the Sweet and Sour Beef, which he liked very well. My 9-year-old daughter ordered Fried Tofu and the Crispy Wings appetizers as her meal. She loved both. My mom ordered her favorite... More

Went because of previous reviews. The spring rolls were good (best part of meal). Ended up choosing the recommended specials. Roasted chicken was greasy and not that good. Other dish was basically a stir fried onion, celery, noodles and a few shrimp and little chicken. The big issue was taste. Neither dish had it. For those who eat Thai frequently,... More

Very small unassuming building that seats 48 people. Nothing fancy but they make up for it with the delicious food. Cashew chicken, wanton soup, pork & shrimp wanton hot pot...all delicious!

The authentic Thai meal was certainly good. Me personally desire and require something the will fill a very large void at times. This particular time when dining here for lunch was one of those moments. My meal here was definitely authentic and good. The communication barrier was at times evident during my visit.

this small, intimate restaurant is a little out of the way, and can be hard to locate, but once there the food, decor, and staff make it more than worth your while to take time to find it.

This restaurant draws a diverse crowd due to its chef and the menu items. They will prepare food at "diferent spice levels" and when they say very hot, believe it. Mild is a good start here and most dished have enough flavors to please most palates. Have take friends from out of town here and they too have enjoyed the... More

I love finding the diamond in the rough, when it comes to small restaurants. This was good, but not exceptional. First of all, some reviewers spoke of the neighborhood. It's a bit rundown, but not "rough" like inner city Chicago. Get over it. This is truly a mixed review. The food went from excellent (spring rolls) to so-so (curry). The... More
