Taking a customizable approach to fast-casual seafood, Brown Bag Seafood Co. has grown into a thriving collection of restaurants throughout Chicago and beyond. And that’s a testament to the rigorous quality of the fish and seafood—gussied up with whimsical accompaniments and served at shockingly affordable prices. The decor is reminiscent of a modern fish shack, with plenty of nautical knickknacks to gawk at while lunching. Like a choose-your-own-adventure, the customizable menu allows guests to pick their fish—everything from rockfish and salmon to curry fish cakes—and then choose their format, be it a salad, sandwich, tacos, or a Powerbox loaded up with brown rice, quinoa, and wheat berries. Or you can opt for a pre-designed staple, like a salmon salad or a buttery lobster roll in a toasted New England-style bun with truffle parmesan tater tots.
