Tha Maharaj is a recent hang-out space in Bangkok city. It is located on the bank of Chao Phraya River (The main river in Bangkok) where is not far from Wat Phra Kaew (the famous temple for locals and tourists). It has restaurants, cafe, ice cream and cake shops as well as open spaces for people to sit and relax. It opens from 7:00 to 22:00. In my opinion, the best time to visit there is the late afternoon through evening so we can see the sunset across the river. More information: how to go there can be found on its official website.
