Sep 06, 2026"The restaurant specializes in northeastern "Isan" Thai style food. Plenty of dishes to pick from the manu. The taste is alright. Sour and sweet is the leading flavours in most dishes we ordered. Spicy salad with grilled chicken tastes yummy with abundant of herbs, "Nam Tuk Gai Yang" which goes well with steamed sticky rice. Grilled beef is not that tender but also not too chewy. The price is affordable ranging from 80-100 baht per dish."

Jul 25, 2026"⭐ Google Maps Review for Tum Nak – ตำหนัก อาหารอีสานรสแซ่บ 25 RCA Alley, Bang Kapi, Huai Khwang, Bangkok 10310 If you’re on the hunt for fiery flavors, crispy bites, and true northeastern Thai soul food — look no further than Tum Nak at RCA. This hidden gem serves up Isaan food that hits hard with both flavor and nostalgia. The must-try dishes: Fried 3 layers pork with Garlic & Chili: The crunch is real. Every bite is packed with roasted garlic, fragrant herbs, and just the right level of spicy kick. Addictive is an understatement! Deep-fried Shrimp Pancake (Tod Mun Goong): Golden, light, crispy outside — juicy sweet shrimps inside. Perfectly executed. Tam Soui (Bamboo Shoot Papaya Salad): Wildly aromatic and spicy, layered with textures from lotus root, crunchy pork skin, and soft-boiled eggs. It’s funky, fresh, and fantastic. Grilled Pork Neck (Kor Moo Yang): Smoky, fatty, tender, and perfectly caramelized. Dips beautifully in their tangy nam jim jaew. Cockles (Hoy Kraeng): Served simply steamed with potent green seafood sauce — briny and bold. Larb Ped: A classic, but they do it right — tangy, herby, and umami-packed with roasted rice powder for the crunch. Sen Lek Luak (cooked medium sized Noodles with Pork Crackling): Yes, even the side dishes here are full of surprises. Light but satisfying. Ambience & Service: No-frills, street-style seating with stainless steel tables and blue plastic chairs. But trust me — once the food hits the table, nothing else matters. Fast service, hot plates, and a full-on Isaan experience. Perfect for groups or a casual food adventure. Final Verdict: Tum Nak isn’t just another Isaan joint. It’s a flavor-packed experience that delivers consistency, spice, and comfort in every dish. Whether you’re a chili chaser or just love the depth of Thai cuisine — this place should be on your map. I’d easily rate this a solid ."
