Dinner plans? Solved. Meet The Ogre: stacked with Tiger Sauce, caramelized onions, raw onions, and beer-battered onion rings for the perfect mix of sweet heat and crunch.

This is the kind of burger you need two hands and extra napkins for.

That sauce drip should tell you everything you need to know.

Backslash Sauce is available by the bottle for $7 so you can take the tangy chipotle magic home with you. Grab a bottle this weekend when you’re at Backslash Burger and keep your fridge stocked accordingly.
