It's not all about the free samples at Costco. Members are also somewhat obsessed with the items at the warehouse's popular food court.
Items change from time to time, but are not always welcomed. That's because when something is added, another item is usually taken away.
As The Seattle Times first reported, the Polish dog is coming off the menu at most locations. However, the $1.50 hot dog and soda combo isn't going anywhere (Costco sold 137 million of them last year).
So what's new? Costco has been quietly rolling out acai bowls at its warehouses across the country.
The $4.99 bowls are vegetarian-friendly and about 330 calories. The frozen acai berry looks like soft serve and comes with fresh strawberries, blueberries, dried bananas and granola with almonds.
At least one Costco location reported dropping the very berry sundae to make room for the new acai bowls, the San Luis Obispo Tribune newspaper reported Tuesday.
According to some comments on Costco's Facebook page, not everyone is happy about the change.
"It’s actually disgusting!!!! It is beyond me why you would get rid of those amazing strawberry sundaes for this!!! It tastes awful and is way more expensive!!!" wrote Abby.
Costco has also introduced an al pastor salad at many locations - also vegetarian. The $4.99 salad is made of plant-based protein (soy), romaine lettuce, black beans, banh mi vegetables and dressing.
And last summer, Costco began testing a 1/3 pound cheeseburger that was supposed to be similar to Shake Shack. It sold for $4.99 and came in at a whopping 1140 calories.
Costco leaders say they get a lot of requests from customers in their comment dropboxes and they will take them all into consideration.
