Walk down Milwaukee Avenue in Bucktown and you might miss it if you aren't looking. It’s a low-slung building, once a cramped garage and gas station, that now pulses with the smell of caramelized plantains and Salsa Lizano. This is Irazu Costa Rican Restaurant & Catering, a place that’s been defying Chicago’s "deep-dish and hot dog" stereotypes since 1990.
Most people think they know Latin food. They expect the heat of a habanero or the heavy cumin of a Tex-Mex plate. Costa Rican food—comida típica—is a different animal entirely. It’s humble. It's balanced. Honestly, it's basically the ultimate comfort food for people who didn't know they needed a "Pura Vida" lifestyle adjustment.
The Myth of the "Spicy" Menu
Here is the first thing people get wrong about Irazu: they expect a fire-breathing menu.
Costa Rican cuisine isn't about burning your taste buds off. It’s built on "peasant food" roots—simple, high-quality ingredients like black beans, white rice, and fresh cabbage. If you’re looking for a spice-induced sweat, you’re in the wrong place. But if you want a Pepito Sandwich that has been the undisputed king of the neighborhood for thirty years, you’ve arrived.
The Pepito is legendary. It’s thin-sliced steak (or chicken, or even tofu for the vegetarians) grilled with onions and tucked into French bread. It's not fancy. It’s just right. Some regulars have been eating it since Henry Cerdas, the current owner, was a teenager washing dishes in the back. Henry’s mom, Miriam Cerdas-Salazar, started this whole thing because she was tired of her low-wage cafeteria job. She saw a "For Sale" sign across from her bus stop and jumped.
That leap of faith turned into a Chicago institution.
Why the Casado is the Real MVP
If you want to eat like a Tico (a Costa Rican local), you order the Casado Dinner.
The word casado means "married man." The story goes that when men got married, their wives would pack them a massive, balanced lunch to get them through the workday. At Irazu Costa Rican Restaurant & Catering, this platter is a mountain of food. You get your choice of protein—the skirt steak is a heavy hitter—served alongside Gallo Pinto.
Don't call it just "rice and beans." Gallo Pinto is the national heartbeat of Costa Rica. It’s a specific blend of rice, black beans, bell peppers, onions, and that sweet-savory magic known as Salsa Lizano. Add some sweet fried plantains and a vinegary cabbage salad, and you have a meal that feels like a hug from someone’s abuela.
The Drink You Can't Skip
You’ve gotta try the Oatmeal Shake.
It sounds weird. I know. Drinking oatmeal? But at Irazu, the Avena Shake is a creamy, cinnamon-spiced revelation. It’s thick, chilled, and weirdly refreshing after a salty plate of Chifrijo (that’s fried pork, beans, rice, and avocado served in a bowl with chips).
Catering and the "Pura Vida" Wedding
Believe it or not, this Bucktown staple has become a massive player in the Chicago wedding scene.
Most wedding food is, frankly, forgettable. Rubbery chicken and dry rolls? No thanks. Irazu flipped the script by offering a full-blown Costa Rican buffet for events. They focus on simplicity and quality. People actually talk about the food at these weddings.
They do these "Fiesta Trays" that are basically a party in a box. You can get a tray of a dozen empanadas—beef and potato, spinach and cheese, or even chicken and mango—and it’ll disappear in five minutes. Their catering team, led by the Cerdas family, handles everything from tiny office lunches to 75-person private dinners in their expanded indoor-outdoor patio space.
The Weird Quirks You Need to Know
Listen, Irazu is a "vibes" place, but it has some rules.
- It used to be cash-only. For decades, you had to hit the ATM before showing up. While they’ve modernized a bit with cards and online ordering, the "old school" soul is still there.
- BYOB is the move. They have a liquor license now, but the BYOB spirit remains part of the charm.
- The Mural. That Costa Rican scene painted on the wall isn't just decor. It’s a piece of history from when the restaurant was just a tiny room.
- The "Cerdas" Sandwich. Named after the family, this Caribbean pork sandwich is basically a grease-soaked masterpiece. Don't eat it if you have a marathon to run later.
Is it Still "Authentic"?
Some people on Reddit complain that the flavor isn't an "explosion."
But that's the point. Costa Rican food is meant to be reliable. It’s soulful. Henry Cerdas has fought hard to keep his mother’s original recipes exactly the same. He even sent his general manager to Costa Rica for cultural immersion. You can’t fake that kind of dedication.
The restaurant faced a massive hurdle during the pandemic, nearly closing its doors. Henry made a public plea to the neighborhood, and Logan Square/Bucktown responded by ordering so much food the kitchen literally ran out. That’s the kind of loyalty this place inspires.
Actionable Tips for Your Visit
If you’re heading to Irazu Costa Rican Restaurant & Catering, do it right.
- Go for Brunch: The breakfast Casado with eggs and Gallo Pinto is the best way to start a Saturday.
- Order the Patacones: These are double-fried green plantains. They are starchy, salty, and perfect for dipping in black bean sauce.
- The Secret Sauce: Ask for extra Lizano. It’s a brown, slightly sweet, slightly spicy vegetable sauce that Ticos put on everything.
- Check the Patio: Even in the "chilly windy city" months, the indoor/outdoor space Henry built feels like a tropical escape.
The best way to experience Irazu is to lean into the "Pura Vida" mindset. Don't rush. Bring a bottle of wine. Order the Pepito. And definitely, under no circumstances, leave without a slice of their rum cake.
Next Steps:
Check their current hours before you head out, as they sometimes close for private catering events. If you're planning a party, look into the Fiesta Trays—they are significantly more cost-effective than ordering individual entrees for a group. Finally, make sure to try the Tacos Ticos, which are rolled and fried like taquitos, topped with a specific cabbage and mayo-ketchup blend that is pure nostalgia.
