If you work in the restaurant or baking business, chances are you have heard of or have purchased items from Chef Rubber. They carry a wide selection of items (i.e., baking equipments, cooking tools, molecular gastronomy ingredients, rare or hard to find cookbooks).
Most of the people do business with Chef Rubber through online purchases, but they do have a physical location in Las Vegas (even if it is located in a non-descript commercial building with a really small Chef Rubber logo. Taking a cab here is possible, but not recommended, as trying to get a cab on the way back is difficult without calling for one from dispatch.
They also offer classes, like chocolate and pulled sugar, taught by some very talented pastry chefs. I know Chef Jin Caldwell (world class chocolatier and Head Chocolatier at Ethel M's) have taught the chocolate classes here (not sure if she still has the time to teach here). But these are geared towards industry professionals that want to improve their skills.
I can literally spend an entire afternoon just looking at all the cool stuff on their shelves. But prices for items is definitely not cheap. But what you get in return for their healthy markups is the wide selections under one roof.
Location: 3/5 Worth the drive if you live in Las Vegas. Otherwise just buy it online and have it shipped.
Price: 2/5 Pricey.
Selection: 4.5/5 They have a lot of stuff!
