30 Chefs Reveal Restaurant "Red Flags" That Indicate You Should Eat Somewhere Else

XxcontaminatexX is one of the people who replied to the post. "I've only been a cook for [about] seven years now," the humble Reddit user told Bored Panda.

"From what I've seen during this time, restaurants should pick up the slack when it comes to product dates."

In fact, that's exactly the red flag XxcontaminatexX mentioned in their initial comment. "The first thing they told us in culinary school when you're learning food safety is: if you enter a seafood restaurant and smell fish, leave."

To save their supplies from the bin, restaurants may freeze them. And this isn't necessarily a red flag! Contrary to popular belief, not all frozen foods are bad for you, and many frozen ingredients can be a key part of a healthy meal.

The act of freezing doesn't make food healthy or unhealthy—a lot depends on the nutritional content of the food that gets frozen. Frozen fruits and vegetables, for example, can be just as nutrient-dense as their fresh counterparts. 

Edward Meier, a former Chef in Resorts at Myrtle Beach and Mackinac Island, said restaurants might freeze their food for other reasons too. "By freezing food you can cook it in quantities large enough to keep the cost per portion reasonable," Meier explained. "Cooking in large quantities then portioning and freezing it, you can hold it ready for service, cutting prep time to the minimum needed to reheat it."

Meier said that most restaurants try to cook from scratch at time of service whenever possible. But some foods take much more time to prepare for service. "For example, you go to an Italian restaurant with a friend who orders pasta primavera while you want lasagna. The pasta dish can be assembled and served relatively quickly but making one serving of lasagna from scratch would take much longer and cost per unit would be high. Whether you make the pasta order wait on the lasagna to go out together or serve the pasta and make the lasagna eater wait on service so they are forced to watch the other customer eat while they wait, you are not going to have happy customers."

"By making lasagna in large quantities then portioning and freezing it, the loss in flavor is minimal but being able to heat it up while the pasta dish is cooked fresh means both orders can go out at the same time," the former chef said. "This way the customers eat as soon as possible, making them happy and turning the table over quicker so you can serve more people sooner. Win win. It also means the cost of making the lasagna is cost effective meaning you can charge less but still have a profit margin high enough to justify offering it on the menu."

I guess, the important thing to remember when looking out for red flags in restaurants is you have to be mindful. Serious issues aside, use your best judgement and if you're unsure about something, you can always ask the staff about it.
