Absolutely delicious! We got the sampler appetizer and everything was great. My husband got the basil duck and absolutely loved it. I got the street fried rice and really enjoyed it. Staff was really friendly and attentive. We got the mango rice to go to try and we will definitely be back to try more of the menu! The place was also very clean which is a plus!!
Overview
Discover Soi 4 Thai, a compact Thai restaurant at 5023 Competition Dr, Bettendorf, IA 52722, United States, bringing fragrant curries, wok-fired noodles, fried rice, soups, and regional Thai specialties to the Quad Cities. From a food blogger’s perspective, Soi 4 Thai distinguishes itself through bold seasoning and dishes that reach beyond the standard Americanized Thai lineup. Customers familiar with Thai cooking have particularly praised the restaurant’s flavors, while its small, clean dining room gives the experience an intimate neighborhood feel.
The menu covers noodles, curries, fried rice, salads, soups, appetizers, vegetarian dishes, desserts, and several house specialties. Current delivery-menu pricing lists Pad Thai around $19, Spicy Basil $19, Thai Fried Rice $19, and Khao Soi about $20 before delivery-platform markups. Crab Rangoon starts around $7–$8 depending on ordering method. Dine-in, delivery, curbside pickup, Wi-Fi, parking, wheelchair accessibility, card payments, and pet-friendly service are currently listed. The restaurant generally opens for lunch and dinner Wednesday through Monday, with Tuesday closed.
A signature choice at Soi 4 Thai in Bettendorf is the Khao Soi. This Northern Thai noodle soup combines a curry-rich broth with chicken or beef, soft noodles, crunchy wontons, pickled cabbage, red onion, crispy garlic, cilantro, and scallions. The result delivers creaminess, spice, acidity, and crunch in the same bowl. Customers repeatedly mention the Khao Soi positively, and one recent diner praised both the food and service after ordering it with chicken.
The Fiery Pad Thai is another strong order for diners who enjoy heat. Rice noodles absorb the savory-sweet sauce while egg, bean sprouts, scallions, and peanuts add texture. A June 2026 delivery customer described the Fiery Pad Thai and Crab Rangoon as “bursting with flavor” and specifically praised the generous portions.
For something less familiar, consider the Crispy Pork Belly or Basil Duck. Reviews praise the pork belly for combining tender meat with a properly crunchy exterior, while another customer said the basil duck was thoroughly enjoyed alongside street fried rice. Mango sticky rice and Thai custard with sticky rice provide a sweeter finish and add welcome authenticity to the dessert selection.
The atmosphere at Soi 4 Thai is cozy, clean, and casual. Because the dining room is small, one reviewer noted that seating can feel cramped and less comfortable during busy periods. That limited space is the main practical drawback for larger groups.
There is also an important current consideration: a July 16, 2026 Scott County inspection cited 11 risk-factor violations, including cooling, temperature-control, and date-marking issues. Diners concerned about food safety may want to check the restaurant’s most recent inspection status before visiting.
For anyone comparing the best restaurants in Bettendorf for distinctive local dining experiences, Soi 4 Thai offers compelling Khao Soi, flavorful noodles, regional specialties, generous portions, and warm service. Call +1 563-296-9058 before visiting and explore a Thai menu with considerably more personality than the usual takeout lineup.

First time here. So delicious and flavorful + quick service. The waitress was very attentive and the food was amazing. I got the tom khan soup with chicken and my friend got spicy pad thai. Fresh and tasty thank you
I lived in the same city for 22 years, and I accumulated a long list of restaurants that I would (more in theory than in practice) recommend to visitors. I've been living in the quad cities for three years now, and I have places I like to eat, but not many I would point to and say, "When you come here, you Have to have a meal there." This unassuming little restaurant makes me feel like a local, because I finally have a great place to recommend to outsiders. Between three people, we ordered three appetizers and three entrees, and everything was incredible. I don't think I can overstate how good the food was. The portions are large enough to feed you for two mealtimes, but good luck having the self control to not clean your plate. Since I've never been to Thailand, I can't speak to the authenticity, but I did notice at least one spot on the menu where the chef references a meal from their hometown (I'll have to order it next time!). I can't wait to come back, and while I hope they get more customers (only 31 reviews??), I also kind of want to keep it to myself!! But food this good deserves to be shared.
Very nice and clean restaurant. We enjoyed the egg rolls, Khaoi Soi w/chicken and another chicken dish that I forgot the name of.
If you haven't had Thai custard and sticky rice you are missing out on a sweet lightly salty masterpiece. I could eat this everyday and twice on Sunday. The janla and the larb are both amazing. If you want to try Thai food without the American twist get either of these dishes and finish up with the custard.
Great little place. Good food, fair prices. Fast service. Easy walk from the Tesla Supercharger.
Soi 4 Thai is a cozy, small restaurant that impresses with its cleanliness, warm atmosphere, and exceptional service. The staff is attentive, friendly, and truly makes you feel at home. The tamarind chicken is crispy and sweet but not too sweet. The mango curry- a perfect harmony of sweet, creamy, and savory flavors that will leave you savoring every bite. Their crispy pork belly—a masterpiece of tender meat with a perfectly crunchy exterior. We also enjoyed the papaya salad and tom yum soup as well as the chicken satay paired with a delicious peanut dipping sauce. Everything was delicious and we can’t wait to go back! Whether you're a Thai food enthusiast or a first-timer, this spot will exceed your expectations. Highly recommend!
Half Thai, so I grew up with my grandmother’s cooking and can attest that Soi 4 is legitimately good Thai food. We got the duck pad see ew, tamarind chicken, chicken satay, and papaya salad and legitimately loved every dish. Great food with great service at an agreeable price? Can’t be any happier having this place close by. Highly recommend!
