Seafood and fast food don't typically go hand in hand, but the folks at Brown Bag are trying to change that. The quick-service restaurant has five locations throughout Chicago—from the Loop to Roscoe Village. Simply pick your protein (salmon, crispy cod, curry fish cakes, seared tuna, etc.) and a base (veggies, grains, salad, tacos, etc.), and you'll be on your way in no time. The fish here is deliciously fresh, whether you go with the daily catch or the grilled shrimp. And you can't beat the price: Most meals come out well under $15.
