Before fishermen discovered the edibility of fish, they used each catch as bait for larger species, hoping in the end to hook the biggest fish of all—friendship. Cast out your line with today’s Groupon: for $10, you get $20 worth of seafood and more at Flying Fish’s Memphis location.

Flying Fish flips heart-healthy sea fare onto every table from a bountiful menu of catfish, tilapia, crab, and shrimp dishes inspired by east Texas's many lakeside eateries. Hook your jaw into a fried crawfish po’ boy sandwich ($8.99), or haul in a net of 12 jumbo shrimp in a basket served with fries and hush puppies ($16.99). The grilled red snapper fillet surrounds itself in a buffer of grilled vegetables, beans, and rice ($10.99) that wouldn't stand a chance against a full pound of armored snow-crab legs trained by arctic kickboxing champions ($14.99). Diners can also fill up on terrestrial edibles such as the chicken salad ($7.99), hot wings ($5.99 for six), and cheeseburger ($5.50).

Seafood fanciers clink forks amid checkered tablecloths and kitschy touches such as the Liar's Wall, filled with playfully hyperbolized “big catch” photos. On another wall, a chorus of Big Mouth Billy Bass singing fish adopted from area families can collectively belt loud enough to roust sunken ships.
