If you're planning a one-day trip to Bangkok, the Chao Phraya River and the Grand Palace are definitely must-visits. Nowadays, travelers have high expectations for a well-rounded experience—they want to eat well, have fun, shop to their heart’s content, and make the most of their time without feeling rushed. This requires careful planning of your entire itinerary.
The route we recommend today includes the vibrant Thai neighborhood of Thonglor (Thonglor), the Michelin-starred restaurant Somtum Der (Somtum der), the Erawan Shrine, the Grand Palace, as well as the River City Shopping Mall and, to top it all off, a cruise on the Chao Phraya River (Supanniga Cruise). 
On this itinerary, you and your friends can start the day just like the locals, walking along the famous Thonglor streets to experience life in Bangkok’s upscale district. Nearby, there’s alsoDonkia Japanese mall. After a morning of exploring, you can recharge at lunchtime at the Michelin one-star restaurant Somtum Der (Somtum der), then head to the Erawan Shrine to pray for good luck (don’t forget to come back and pay your respects if your wishes come true), followed by a visit to the Grand Palace. After your tour, you can go shopping at the River City Shopping Mall (River City), and then board your pre-bookedSupanniga Cruisecruise while enjoying dinner.
Highlights:
For lunch, Somtum Der (Somtum der) is a famous Michelin one-star restaurant that has been a hotspot since 2016, with branches in cities like Tokyo and New York. It’s highly renowned. A must-try is their high-quality signature green papaya salad. The restaurant not only preserves the flavors of traditional Thai cuisine but also showcases the chefs’ creativity, earning a wealth of five-star reviews. Recommended dishes include secret recipe salted egg papaya salad, flavored rice noodle papaya salad, and Northeastern-style salad. You can also pair these with their signature sour and spicy pork rib soup or the special fried chicken (this fried chicken is so popular it even has lines at the New York branch). Somtum Der’s sister branch in Thonglor (Supanniga) is also nearby and can serve as an alternative (Michelin restaurants are often packed, so plan ahead), but if you’re lucky, go for Somtum Der—this way, you won’t miss dinner at Supanniga Cruise in the evening.
Supanniga CruiseUnlike other group tours’ Chao Phraya River cruises, modern travel trends lean toward a more luxurious and exclusive experience. Young travelers prefer comfort, privacy, and relaxation over competing with large tour groups for space. That’s why Supanniga Cruise isn’t your typical crowded tour boat—it’s a fine-dining cruise created by the Supanniga Group, with only 40 seats. Onboard, you can enjoy the sunset while sipping on the famous Taittinger champagne (a must-order) or your favorite cocktail. The cruise is semi-open, and the dishes feature traditional northeastern Thai cuisine—an understated form of luxury. This level of experience is unmatched by other cruises, which is why you’ll need to book it in advance through platforms like Ctrip or Qunar.
