I visited this place and noticed that it attracts more tourists than locals, despite the fascinating story of the house and the fame of Thai silk-making. Inside are different sections, including a guided tour of the place in foreign languages (English, Chinese, and Japanese), a cafe, a brand shop, and a renovated restaurant. The admission fee is only 200 baht, and the tour lasts 45 minutes.
The atmosphere at Jim's in Thompson felt shady as if it's not in Bangkok. The food and drinks at the cafe were alright, but I found the prices a bit high for the portion sizes. On a positive note, there's a rotating exhibition on the second floor of the brand store, and it's free to view.
