Tay Buan Guan

Tay Buan Guan was a popular supermarket in Katong in the past. It was one of the earliest supermarket to be opened in Singapore. It was opened by Tay Leck Teck in 1948. Tay Buan Guan had a Chinese emporium, a costume jewellery shop and a pharmacy within its premises as it occupied a lot of space. The Chinese emporium was called the "Singapura Emporium". The emporium occupied the 1st floor of Tay Buan Guan. The ground floor and 2nd floor were occupied by other departmental shops while the 3rd floor was occupied by the sky garden. A confectionery was added to it, which made it famous for its cakes and pastries. Its founder, Tay Leck Teck, passed away in 1980 at the age of 80. The 1st floor of Tay Buan Guan provided facilities such as banking, and had shops selling jewellery, clothes, flowers and pets. However, when shopping centers started opening in Katong, Tay Buan Guan started to lose its business and finally wound up in 2000. It was separated into sections and sold to others as shop houses. Its entrance is now said to be occupied by the shop called “Rumah Bebe”, which is a Peranakan heritage house. It is said to be the entrance as the pillar with the faint TBG print on it.

However, based on the blog "Times of my life", the real entrance seems to be the unit #83 which is occupied by Greentown Audio Video instead of unit #113 which is occupied by Rumah Bebe.
However, if Rumah Bebe is not the real enterance to Tay Buan Guan, then many sources would have been wrong, such as the URA walking guide and the Singapore Infopedia.
