Duke's Seafood South Lake Union

Last checked Feb 19, 2026
Duke's happy hour is a solid "meh." Drinks and food both offer decent, but not dazzling, average savings. You'll save a bit, but don't expect to be wowed.
The food deals are similarly uninspired, averaging 16% off 18 items. Offerings like the Dungeness Crabby Deviled Egg at 22% off or The Duke Cheeseburger at 20% off are the best you'll find, with many items like the Clam Lover's Steamer Clams at a paltry 11% off. It's slightly better than nothing, but not by much.
The drink deals average a mediocre 18% off across 21 items. While you can snag 20% off a Cucumber Mojito or Sunny Slope Nectarine Mule, most cocktails hover around 19% savings. It's fine, but not a reason to rush over.
