Royal Osha Restaurant

Thai Fine Dining with Style

Royal Osha is one of the most refined Thai restaurants in Bangkok, known for serving traditional Thai cuisine with a modern presentation. It’s no longer just about luxury or showy interiors – this restaurant has matured and now stands as a serious culinary destination in the city. Royal Osha has been recognised by the Michelin Guide Thailand with a Michelin Plate for several years, highlighting its consistent quality.

The restaurant is located on Wireless Road, near the entrance of Soi Ruamrudee and opposite Lumphini Park in Ploenchit. The building is easy to spot – a large and bold structure with dark glass and dramatic lighting. From the outside, it still looks like a high-end venue that could feel too formal, but the second you step in, the staff makes you feel welcome.

The décor is impressive – tall ceilings, rich fabrics, and a large golden Thai crown suspended above the central bar. There’s a mix of modern and traditional details that might look a bit theatrical, but with a full dining room and warm lighting, it works well. The two floors can accommodate quite a lot of guests, and on our last visit, most tables were full, with a mix of locals, diplomats, and well-dressed international visitors.

The new head of the kitchen is Chef Vichit Mukura, a well-known figure in Thai culinary circles, who previously led the kitchen at The Thai Restaurant at The Mandarin Oriental for over two decades. His influence shows. The food is carefully prepared, with attention to detail and balance. It looks modern, but the flavours are deeply Thai and authentic – there’s no unnecessary fusion here.

The tasting menus (from 1,890 to 3,590 baht per person) focus on rare and seasonal ingredients from different regions of Thailand. For à la carte, there are familiar Thai dishes with refined touches. One of their signature starters is the Miang Kham Bai Cha Plu, served on betel leaves with dried shrimp, peanuts, and a delicate tamarind sauce – presented like canapés. Another memorable dish is the Tom Yum Goong Mae Nam – the famous prawn soup is here elevated with giant river prawns and a clear broth, cooked to perfection.

We ordered the Steamed Sea Bass with Chilli and Lime Sauce, which was fresh and tangy, and the Crab Curry with Betel Leaves, a southern Thai dish full of flavour and just the right amount of heat. We also tried the Khao Yum Dok Anchan, a colourful blue rice salad with local herbs and edible flowers, which tasted as good as it looked.

The service is smooth, professional, and friendly. The team speaks good English and doesn’t overdo the formal tone – they check in when needed and give you time to enjoy the meal. The wine list is not too extensive but includes some smart choices at fair prices for a fine dining restaurant.

Royal Osha has improved a lot since we first visited years ago. It now feels like a well-run, confident Thai fine dining venue that puts flavour first and supports local ingredients. Prices are high but fair for the quality of food, presentation, and service. It’s ideal for special occasions, business dinners, or when you want to introduce visitors to refined Thai cuisine.

We’ve returned a few times recently, and each time was consistent. Our last visit was to try their famous Khao Chae, a famous, delicate summer dish in Thailand. This is the kind of restaurant we now recommend to friends who want to experience authentic Thai food at a high level, without compromising the essence of Thai cooking.

Khao Chae at Royal Osha

Among the many Khao Chae we tried recently in Bangkok, the one at Royal Osha was probably the best. It was the most expensive at 1,250 baht, but the quality and detail were impressive. The jasmine rice was soaked in chilled, flower-scented water and served with seven side dishes, all beautifully arranged. We especially liked the shrimp paste balls, the stuffed shallots, and the sweet preserved radish. Each bite had the right balance—nothing was too salty or too sweet.

The rice water had a clean, gentle aroma that wasn’t too strong. They also added carved vegetables and fruits, which made the set feel quite special. The presentation was refined but not overdone. While it’s not something we would eat often, it’s a great way to enjoy this classic summer dish in a more refined style. If you’re curious about palace-style Khao Chae, this one is worth trying once.
