Food is good but it took forever! And the service is horrible. The boss lady was very rude to the customers, very bad attitude and arrogant. She was so nice when there wasn’t busy but turned into a devil when the restaurant is packed. You are not allowed to ask for your forgotten orders otherwise she will start yelling at you and treats you badly. There’re plenty of better restaurants in Frankfurt. Not recommended at all.

15 years ago, this was the most authentic Thai resto in Frankfurt. That might not be true anymore. My fried rice didn't taste like it does in Thailand, but it was still delicious, and this place is still on the old pricing, which makes Udon a budget friendly. Be aware they do NOT accept credit cards.

The service are great and the food are delicious but it is not the one I am looking for because it a fusions thailand food. SOM TAM still great but I am not recommending the kra prow because it will not taste like what you have eat it in thailand

I ordered 2 Pad Thai, 1 Tom Yum Gung and 2 Thai ice tea. They're basically common dishes in every Thai restaurant/Imbiss. I've tried roughly 10 Thai restaurant/Imbiss in Germany, but this one is definitely the worst. Wasted 30€ for under-average dishes. They undermined the reputation of Thai food.

If you are looking for real Thai food this is the place! Good quality of food, very friendly staff and good prices.

Good service and friendly staffs. German adjusted thai food with average taste, maybe because I didn’t order from their recommended menu. Price is good especially if you order from the standard menu. Nothing to complain, but I had other better authentic Thai place. Make sure to order crispy chicken on top, it’s delicious.

Oh this is the best Thai restaurant in Frankfurt. Just look at the food.

Best menu : pad thai, tom yum soup & pork ribs. The fried rice required improvement. Space & ambience : OK

The Best thai restaurant which is tasted like in Thailand.

This tiny restaurant never disappoints. I have been here countless times for lunch, super consistent in taste and quantity. Multiple vegetarian/vegan options. The food is an addiction and staff is extremely friendly.

Great place and great food! So far, definitely my favourite Thai Restaurant in Frankfurt. It looks really authentic and the food was great. I ordered fried duck with red curry and vegetables and my wife ordered Pad Thai, and both were really delicious. Definitely the best Pad Thai we tried in Frankfurt. After our trip to Thailand, we tried Pad Thai at few places in Frankfurt, but no one was even close to original taste and I thought we will not find good one until we came to Undon. I can't wait to come again and try other dishes. 🙂
