We had a lovely stay at the Renaissance Johor Bahru, which is a fairly new five-star hotel popular with both business guests and families (see pics of the rooms and facilities here). One of the bonuses of staying there is having a fine-dining Chinese restaurant right on site. Wan Li serves Cantonese with modern touches and isn't afraid to borrow ingredients from other cuisines to give dishes a lift beyond the usual renditions.
The kitchen has been inspected and the food deemed suitable for Muslim consumption. They just can't have a halal license because they carry liquor. "Lots of Muslims actually like Chinese food," the restaurant told us.
