Time Out says
Most guides to Klang bak kut teh begin with Seng Huat (also famously referred to as the ‘bak kut teh under the Klang bridge’), and for good reason. One of the earliest bak kut teh joints around, Seng Huat doles out traditional bowls of tender meat with aromatic broth. Mushrooms, tofu and yao char kuey are available upon request at this media darling. If possible, get a table under the bridge and have bak kut teh as the occasional train trundles by.
