Fun times! Le Cordon Bleu classes are a great way to do something new around Vegas. Especially in the middle of the summer when you don't want to be outside.
There are a ton of different classes and workshops so you can find whatever interests you or something you want to learn more about. Besides cooking they have numerous technique courses such as knife skills, etc.
What may turn people away (or prevent them from finding it in the first place) is their website. It is not very user friendly and rather difficult to find a straight forward listing of what classes are available. If your patient you'll eventually find it. Keep in mind that some 'limited time only' classes aren't shown but will only be displayed as you delve further into signing up.
Cost is also a factor since they're not cheap. But I will say you come away with a ton of food to take home! So weight that when you make your assessment.
I went to the Hundred Foot Journey class which, like the movie, is a theme of French and Indian with some overlap (cardamom crème brulee). The instructors were friendly and helpful and gave good tips. The students who helped clean, set-up were great too. That class was overbooked sadly so we had to team up with a partner. Which was fine but you also end up with half the food you'd get on a few of the things.
