About
Zabb One at Ratchada Soi 5 is a separate shop from the Zaap One opposite Big C, sitting at the Din Daeng end of Ratchadaphisek, closer to MRT Phra Ram 9 than to Huai Khwang. GrabFood's 20-restaurant Ratchada roundup includes it and recommends the tom saep pork-bone soup, minced pork larb and som tam, with a price tier of two out of four, which means an everyday Isan place. Hours are 10:00 to 22:00 daily. Google rates it 4.5 from more than 550 reviews, and Grab, in a write-up dated April 2025, gives 4.6 from 122 and calls it another popular Isan kitchen on Ratchada whose signatures are seasoned hot. The som tam in particular comes very spicy, so ask for less chilli if you need to. The Facebook page Grab links to is named Zabb One สาขาหอการค้า, and the phone is 098 525 7827.
