Best Business Lunch Power Players Mexican Restaurants in Loop

Tortazo is Rick Bayless’s fast-casual Mexican spot inside Willis Tower, focusing on Mexico City-style tortas, chilaquiles, and salads with a full bar in a colorful, design-forward room. Office workers and visitors use it for higher-upgrade tortas, salads, and margaritas that still move quickly at lunch.

A Loop counter-service spot that keeps the menu tight and punchy—tacos, tortas, and a few snackable starters built for fast lunch momentum. It’s at its best when you order like a repeat customer: one starter to share, then two focused handhelds instead of mixing every category.

Asada Mexican Grill is a halal-friendly Mexican counter spot just off Wacker that builds burritos, bowls, tacos, and salads to order. Downtown diners lean on it for customizable Asada Steak Burritos, barbacoa, and veggie options that are hearty enough for lunch but efficient for grab-and-go.
