Seng Huat Bak Kut Teh has been in business since 1979 and is more commercially successful than Restaurant Chuan, which opened in 2008. Seng Huat has more experience in making bak kut teh and has built a loyal customer base, receiving awards for its food. However, it faces issues like dirty environment and cramped space. Restaurant Chuan needs to improve its bak kut teh taste and advertise more. Both businesses could benefit from interior renovations.
