Stepping up its gastronomical tease, Shake Shack is offering its classic burgers and a shake at a downtown pasta restaurant for a few hours later this month.

The burger chain is heralding its arrival in the Central West End at the end of the year by partnering with Porano Pasta, 634 Washington Avenue, from 11 a.m. to 3:30 p.m. Oct. 28.

They will be serving the ShackBurger and 'Shroom Burger and crinkle-cut fries, plus a butterscotch frozen custard banana-oat cookie sandwich created by chef Mathew Rice of Niche Food Group. The full menu for the pop-up event is available here.

Heads up: The event requires registration, which is available here.

It's the first official taste of Shake Shack in the hometown of its founder, Danny Meyer.

Meyer is of the country’s most influential restaurateurs. He announced last year that Shake Shack will open at 32 North Euclid Avenue in the Central West End.

Shake Shack, which Meyer terms “fine-casual” dining, features hamburgers made from antibiotic-free Angus beef as well as crinkle-cut fries, hot dogs and frozen custard. The first permanent location opened in 2004 in New York City’s Madison Square Park. There are now locations in 11 states and Washington, D.C., and also in the United Kingdom, Japan, the Middle East, Russia and Turkey.
