Bethesda’s Hamburger Hamlet is launching a joint venture with Du-par’s, a bakery and coffeeshop that’s been a fixture in the Los Angeles dining scene since 1938.

Du-Par’s Hamburger Hamlet announced the venture on a newly-launched Facebook page. The re-vamped restaurant is set to debut Dec. 1, according to the post, and the eatery will be open 24 hours a day.

The news was first reported by Bethesda blogger Robert Dyer.

Changes will include a new bakery and a combined menu, according to the post. Du-Par’s is known for their breakfasts and fresh fruit pies, according to their website.

Restaurant reps weren’t immediately available for comment on the new venture, but stay with Patch for more updates.
