Burger lovers: This is what you’ve been waiting for.

After much hype, Shake Shack is opening a restaurant in Dupont Circle today. It’s only the third location for the chain outside of New York state.

So, what’s all the buzz about? Shake Shack bills itself as a modern day “roadside” burger stand. In addition to burgers and hot dogs, the restaurant offers frozen custard, seasonal beers, crinkle fries and more — all with locally sourced ingredients.

Lines are so long at its original Madison Square Park store in New York City that Shake Shack has a Web cam , so patrons can time their visits to avoid the crowds.

Praise for Shake Shack borders on the cult-like.

“Best burger in Manhattan. And I will fight anyone who says otherwise,” wrote one reviewer on Yelp. “The cheese: amazing. The meat: amazing. The bun: amazing. The pickles: amazing. The bacon: amazing. Are you starting to see a trend here?”

The Dupont Circle store opened at 11 a.m. It’s at 1216 18th Street NW. A second Shake Shack will reportedly open at Nats Park later this year. Shake Shack is entering a crowded D.C. burger market.
