Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

2012 – December 2025

Chicago Diner opens Logan Square location (2012)

The vegan diner, founded in Lakeview in 1983, opened a second location at 2333 N. Milwaukee Ave. in 2012. It served plant-based comfort food there for 13 years before closing in December 2025.

Then

The storefront sat vacant for about ten months.

Now

Its closure was part of a wave of four Chicago vegan eatery shutdowns in eight days.

Why this matters now

Siete Azul is taking over the exact space the diner vacated, inheriting a proven restaurant location on a busy Milwaukee Avenue block.

2010 — present

Las Islas Marias opens in Wheeling (2009)

The Zendejas family opened a Mexican seafood restaurant on Dundee Road in the Chicago suburb of Wheeling in 2010. It became the family's flagship and training ground for Luis Zendejas, who grew up working there.

Then

Gave the family a foothold in the Chicago restaurant scene.

Now

Its Siete Mares soup and recipes inspired Siete Azul's menu and name.

Why this matters now

Siete Azul is the family's first expansion into Chicago proper, drawing on two decades of recipe and management experience.
