I’ve been to Au Cheval before my gluten allergy, but I have to say— the gluten-free route is the way to go, even if you’re not celiac!
Service was fantastic, and they offer two gluten-free burger options: a hash brown simmered in beef tallow or lettuce cups. I chose the hash brown, which was crispy, buttery, and indulgent, but if you want the meat to shine, go for the lettuce cups.
We also got the bone marrow, and it was to die for—highly recommend! If you’re GF, it comes with lettuce cups; otherwise, you get toast. They offer small (2 bones) and regular sizes—the small was perfect for sharing.
That said, I’d rate the burger meat 7/10 — not quite the holy grail Chicagoans claim. And if there’s a long wait? Probably not worth it.
