Costco is a great place to shop when you're looking to stock up on bulk items, as this member-only warehouse allows you to score great deals on must-have food items such as wine, meat, and fish.

And although saving big is one of the biggest perks of shopping at Costco, expert chefs said that another notable advantage is the quality of items sold at the store.

To help you upgrade your cooking game, here's what eight chefs recommend buying at Costco.

One chef always stops at the Costco butcher counter.

"Costco's butcher counter consistently has stellar cuts and is one of my go-to sections when I visit," said chef Kyle Johnson from BOURBON STEAK in Los Angeles. "It's honestly one of the very few places where you can get restaurant quality meat at an affordable price."

Costco is a great place to get real Parmigiano Reggiano cheese, according to one chef.

"Not many people know this but Costco has real Parmigiano Reggiano, which is a huge score," said chef Jackson Kalb of Jame Enoteca in El Segundo, California. "As a chef focused on Italian flavors, we always buy in bulk for the restaurant and use it in a multitude of our dishes."

One chef buys meat and fish in bulk at Costco.

"I also enjoy Costco if I'm cooking for a party at my house," said corporate chef Daniel England of San Diego's OMG Hospitality Group. "It's a great place to bulk-buy meats and seafood — ribs, steaks, shrimp, you name it."
