Hamburger Mary’s Ontario is your place to Eat, Drink, and Be… MARY! We’re an American bar and grill where diner classics & cocktails meet quirky entertainment.
We Are Temporarily Closed
To our Valued Friends & Family,
We will be temporarily closed until further notice as mandated by San Bernardino County. Our hearts and thoughts go out to all of those affected by the unprecedented events surrounding Covid 19, including all of our staff, entertainers, queens, and DJs who rely on us as a source of their income.
The health of our staff and customers is MOST important. We thank all of our Mary’s Family and friends who continue to support us and we look forward to seeing you all again soon to once again Eat, Drink, and be… Mary! Be safe everyone.
- Nothing today sweetie!
Check our calendar and see what Mary has on deck.
Tasty apps, juicy burgers, and delicious desserts, all served up with a side of sass! Come on in to eat and stick around for one of our nightly events. Mary also cooks up some mean omelettes and other savory and sweet dishes during our Sunday brunch.
