Yong Peng remains the best lunch stop, timing wise, when traveling down to JB from KL. 688 coffee shop is a lively place with 5 stalls, which is considered a high stall count for Yong Peng. There is the drink stall that also sells Bak Kut Teh, Assam fish and porridge. There’s also a chicken rice stall, a Wanton noodle stall, a Tze Char stall and a soup stall (fish balls, pork ribs etc.).
I didn’t snap a photo, but the Bak Kut Teh is actually quite good value at RM10. It came with 4 pieces of pork spare ribs (not frozen pork) and a few slices of pork belly.
If you want variety, i think 688 fits the bill.
