Have a family style dinner at the Bjursta table Ikea built.

The affordable Swedish furniture store with a cult following around both its bookcases and meatballs is now inviting shoppers to an all-you-can-eat crayfish party on September, 15 at select locations nationwide.

“The Crayfish Party is an anticipated celebration in Sweden marking the end of the summer and the official beginning of crayfish fishing season,” Patricia Meumann, Ikea food manager, said in a statement.

And in true Ikea form, the store provides a tutorial on how to properly peel crayfish in its invite.  “Twist off the joints from the claw ends and eat all the visible meat,” the instructions read.

Access to the in-store buffet costs $18.99 per person and $4.99 for kids 12 and under. The colorful menu includes dishes like crayfish, pasta primavera salad, gravlax, Swedish cheeses and, of course meatballs, to name a few.

Corralling the family to eat at the same place you brought your living room rug and the shower curtain might seem a bit odd, but the brand’s food division is booming. In 2015, the store added vegan and chicken Swedish meatballs to the menu to cater to customers’ desire for healthier, better sourced dining options. The change increased sales by 30%, Fast Company reports.

And that’s just adding on to its tasty roster of pre-packaged items like preserves, pastries and jars of herring. The company serves 650 million diners around the globe annually, amounting to about $1.8 billion in sales last year. And believe it or not, almost one-third of Ikea customers come to eat not shop, a small bite of the $36.5 billion the company earned in 2016.

The Ikea eateries even look more posh than a traditional food court, outfitted with lounge chairs, bright white floral light fixtures, sofas and communal tables. And it’s affordable –  a family of 4 can eat for $20.
