Mariscos San Pedro

Pilsen · Mexican Seafood Community-sourced, unverified

📍 1227 W 18th St, Chicago, IL 60608

Mariscos San Pedro took over Thalia Hall's former Dusek's space in Pilsen in 2024, run by the 16" on Center restaurant group that also operates Thalia Hall itself, Punch House, and Tack Room — a genuine neighborhood-concept lineage rather than an outside operator parachuting into the building.

$$$

Monday's 50% off all wine bottles plus $2 cold oysters, alongside a Crab Michelada and Hamachi Aguachile — Mexican seafood from the Thalia Hall restaurant group, in the space that used to be Dusek's.

The menu leans Mexican coastal and seafood-forward, built around dishes like a Crab Michelada, Hamachi Aguachile, mussels, and empanadas, with a chocolate cake and a galette rounding out dessert. The happy hour is real and specific, running daily from 5 to 6 p.m.: a $40 margarita pitcher in mezcal or tequila, a $12 rotating cocktail of the day, a $12 'Agitamanos' beer-and-shot handshake, a $5 rotating shot, and $10 guacamole built with radish, serrano, and cilantro. Mondays go further still, outside the happy hour window entirely — 50% off every wine bottle on the list, all day, plus $2 cold oysters with a six-oyster minimum, which is a serious standing deal for a seafood restaurant to run on its slowest night of the week.

Weekend brunch runs 11 a.m. to 2:30 p.m. Saturday and Sunday, with dinner picking back up at 5, and weeknight hours stay a tighter 5 to 9 or 10 depending on the day. For a space that spent years as Dusek's before closing, Mariscos San Pedro gives the Thalia Hall complex a genuinely distinct new identity — Mexican seafood with its own happy hour and its own Monday tradition, not just a rebrand of what used to be there.
