We went to visit the memorial hall on a public holiday. Entrance for foreigners on that day was free. The memorial hall is not very big about two storeys high and easy enough to navigate around. It is beautifully kept and the exhibits are interesting if you have an interest for Chinese history.
Several other sights nearby like the Burmese Buddhist temple and a Pentecostal church. We commuted to Novena by MRT and took bus 131 which got us within walking distance. Nice to do if you have nothing else planned.
