Tried Thai 9 during my visit to Dayton. The overall vibe is great — cozy, lively, and welcoming. Service was top notch — attentive and friendly without being intrusive. Only thing to note: the spice levels run much hotter than expected. As someone who enjoys and tolerates spice (I’m Indian), I asked for a 6/10 and still found it a bit too hot for comfort. So be sure to adjust accordingly if you’re sensitive to heat. Otherwise, a solid experience and worth a visit!

This place is my favorite place to eat if you’re anywhere near Dayton. The staff have always been nice the food has always been wonderful, and the restaurant it self is beautiful. Im only writing the review now because this is the first time I was able to get some pictures before we all demolished our food. There are literally no bad choices as to what to eat here but there is one required one, you have to get the FBI- its on the dessert menu- its I kid you not the one thing that actively haunts me and forces me to make the drive from where I live in Cincinnati. Entres are around 15-20 a person Apps around 8 Dessert 7

One of my favorite local spots for lunch. The Pad See Ew is my go to but all their food is excellent!

Arriving at Thai 9, we were a little confused as the outdoor entrance is very modest and hidden. Entering the facility though, you will be quick to find out how amazing this place is inside. It’s beyond beautiful and I have still been thinking about it since it went. We were greeted by a friendly worker and were sat promptly. The menu is very big which can always be a little alarming at first, but this is not an issue with this restaurant. We started out with crab Rangoons which were cooked to perfection and the doughy/crunchy texture with the generous filling was amazing! It was lunch time so we ordered one of their lunch specials which included 5 nigiri and a roll. The 5 nigiri were all so very fresh but I have to note that the salmon and white tuna were extra excellent. Also, for my entree I ordered their Pad Sea Ew and my buddy ordered pad Thai. They both came out in a timely manner. Both entrees were easily the best of their kind that we’ve both had. The portions sizes were beyond generous. The spice level can be high but they make you aware of this. I absolutely loved this place coming from an absolute Thai and seafood lover. The absolute game changer though was the price. It was 22 dollars for the pad sea ew and the sushi special which is an absolute steal. Everything was fresh and flavorful! I want to emphasize that waitress Claire was beyond amazing and friendly. Waiter Rob/Ron i don’t remember exactly was also very professional as well. This restaurant is the whole bundle. I will 100% be back here! KUDOS!

I always get the yellow chicken curry, I have sent many people here to have the exact same dish. Today the dish was so salty that I could not finish. ….. I’ve had this dish over 30 times and there has been some times that it’s been too hot because of the chilly oil or too soft because of the chilly oil but never salted.. As I understand, we are all human and make simple little mistakes. I will always recommend this place besides tonight with the saltines and my wife’s fried rice being under seasoned and under flavored it is always a go to spot in Dayton.

⭐⭐⭐⭐⭐ Absolutely incredible! The food was bursting with authentic flavor — perfectly balanced spices, fresh ingredients, and the kind of dishes you keep thinking about long after you leave. The Pad Thai was the best I’ve ever had, and the Green Curry had the perfect kick without overpowering the dish. The staff was warm, attentive, and genuinely kind, and the atmosphere felt cozy and welcoming. Every detail was spot on. If you’re craving real Thai cuisine, this place is a must. I’ll definitely be coming back!
