Although I disagree with the main business of Sampoerna (they sell ciggies), I have to say that House of Sampoerna is one of their good achievements that they can be proud of. It is a museum of how Sampoerna was established, you could be able to see how they started the biz, the "old ways and tools" to dries up the clove and making cigarettes. Also offers free tour around Surabaya (please call and confirm) and has a small café and gift shop.
