It’s easy to lower your sandwich expectations.
Most of us have been burned. Too many limp hoagies and soggy paninis can wear a person down. So when you walk into a place called Proper Sandwich Company, the bar in your mind might still be set to “eh, we’ll see.” That’s where I was. And then Kyle’s Chimichurri Beef happened.

My husband and I walked in expecting a standard sandwich. I walked out questioning every sandwich choice I’ve made this year. How did I not know? Kyle’s Chimichurri Beef isn’t just good, it’s the kind of sandwich that recalibrates your sandwich baseline.
The backstory only makes it better: Three years ago, a then-teenage staffer named Kyle, brought the idea to life after seeing a viral chimichurri sandwich on TikTok. With encouragement from Jeff (the Chicago-native GM who runs the place with remarkable hospitality) and Phil (a seasoned sommelier and also a Chicagoan with Strip cred to match), Kyle’s idea quickly became a full team collaboration.
Phil drew on his roots and fine-dining knowledge, insisting on house-roasted, prime-grade beef slow-cooked and seasoned in the style of Chicago’s Italian beef icons like Johnny’s Beef and Portillo’s. He added sautéed mushrooms for extra depth. What began as a staff experiment turned into a menu mainstay: a collision of inspiration, tradition, and restaurant family.
And you can taste every layer: The beef is tender with a slow-built depth that comes from method. The chimichurri snaps through the bite, its bright acidity, sharp herbs, a clean heat that wakes everything up.
And then there’s the bread. Sourced from our local Pizzeria Monzu, it has that fermented character you can’t counterfeit: crisp structure outside, a slightly tangy warm give inside. That sourdough bread is the scaffolding that holds together the juicy roast beef, french fries (yes, there’s crispy fries in there!) and drippy aioli.

Here’s my take on why the Kyle’s Chimichurri Beef sandwich is so popular. It hits the 5 S’s: salty, sweet, savory, spicy, sour. When all five show up, it wakes up every tastebud in a single bite. It’s why you keep going back for another before you’ve even finished chewing the last.
I promised myself I’d explore the entire menu, but this one has pull. The Chimichurri Beef is the gravitational center of their lineup.
A proper sandwich in every sense.
