342 Bar is another hidden gem with stunning views and an incredibly pleasant atmosphere. The bar is located on the fifth floor of the Baan Wanglang Riverside Hotel, right by the Chao Phraya River, in one of the most picturesque spots. You can enjoy views of Wat Arun, the Rama VIII Bridge, Thammasat University, Tha Tien, and Wat Phra Kaew. It's the perfect place to relax, listen to music, and take in the river in a romantic setting.
