Non muslims can enter the masjid but have to wear aurat covering clothes(available for borrowing).food stalls outside have great choices.my fav resting area and to pray when i am traveling or out.
Mosque is beautiful. To get there about MYR9 on Grab from KK Waterfront. You pay MYR10 to walk around and take pictures, but can only go inside at certain times. Modest clothes available for rent.
