🔥 TODAY'S SPECIAL: TALLOW STEAK BENNY 🔥



🥩 TALLOW STEAK BENNY
A jumbo toasted English muffin piled high with diced sirloin sautéed in our HOUSE-SMOKED BEEF TALLOW, grilled tomatoes, house-made guacamole, 2 poached cage-free eggs, creamy hollandaise and crumbled goat cheese.

The house-smoked tallow gives the steak an incredibly rich, savory flavor — you’ve gotta try this one!

🍳 Breakfast served ALL DAY!

Come hungry. Leave happy. 😋
