Visitors to KL interested in taking a cooking class might consider Bayan Indah, a 'culinary retreat' about half an hour from downtown.
Many locals are familiar with Rohani Jelani, the longtime writer/recipe tester/cooking teacher who runs the classes and owns the retreat, but not so many foreign visitors are, and Rohani is not actively advertising -- so I thought I'd post it here.
Accoms are stylish and comfortable; you can book a class (or not) and also ask that dinner be prepared for you. If I were passing through KL I'd find this a great place to relax and unwind after a couple days in the city.
Also, food/travel photography classes might be offered here in the future.
