Leave it to Anthony Bourdain to spill the restaurant industry's biggest truth bombs. After all, the famous TV personality and best-selling author isn't known for beating around the bush (remember when he shocked us all by saying you don't actually need a knife set?). That's why back in 2001, Oprah Winfrey tapped the world-famous chef to share insider secrets for her show — and some of them just need to be resurfaced.

1. Most restaurants recycle their bread.

Since the first rule of classical cooking is to "waste nothing," Bourdain says if a busboy sees a basket of untouched bread, he'll probably bring it back to the kitchen to serve again later. Hey, at least this means you don't have to feel guilty about leaving a few rolls behind.

2. Hollandaise sauce is a risky order.

Turns out, the raw eggs in this brunch staple are very attractive to bacteria. "Any place that makes hollandaise should throw it out about every hour and make a fresh batch, otherwise it can hurt you," he says. You might want to consider this the next time you order Eggs Benedict.

3. Seafood is freshest from Tuesday to Friday.

Bourdain says most wholesale seafood markets are closed on the weekends and some chefs like to unload what's leftover onto their Monday customers. "So Tuesday, Wednesday, Thursday, Friday, you are more likely to get a fresher, more impeccable piece of seafood. That's when I eat my fish," he says.

4. Brunch is all about the scraps.

Even though Bourdain admits he hates cooking brunch, any cost-conscious chef knows it's a genius way to use up Saturday night's scraps and "charge $14.95 for two eggs," as he puts it. "Brunch offers the dubious benefit of being able to unload one's little odd bits into cute dishes like seafood frittata, seafood salad vinaigrette," he explains.

5. Bathrooms reveal the quality of your meal.

Can you really trust that blue "A" near the front door? Bourdain recommends going straight to the bathroom and taking a look around. If it's clean and tidy, he says that's a good sign — but if it's filthy, he says that's bad news for your meal to come.
