Writer was enjoying an 80-sen sirap limau (lime syrup) at the stalls next to the Masjid Al-Mokhtar, Balik Pulau (district mosque) when writing this short note... The stalls are generally open at about 4-7pm daily. BTW, FREE broadband wi-fi too from the public library next to the this small hut - who needs Starbucks!
The stalls at Pekan Genting however opens till late nite. For a plethora food items and goods, check out the weekly Night Markets on Wednesday and Sunday near Genting between 5-10pm and the weekly Agro Market on Sunday morning near the new Market Complex near Kongsi.
