Added to HapHunt Feb 19, 2026
Duke's Seafood South Lake Union offers a meh happy hour, with both food and drinks averaging under 20% savings. While some cocktails reach 20% off, most discounts are closer to 15%, making it passable but not exciting.
Duke's food happy hour is a solid 'meh' with an average saving of 16% across 18 items. While you might save 20% on The Duke Cheeseburger or the Screaming Good Grilled Chicken Sandwich, and 22% on the Dungeness Crabby Deviled Egg, most items like the Clam Lover's Steamer Clams (14% off) or Heirloom Masa Dusted Calamari (15% off) offer rather modest discounts that won't get your heart racing.
Food Savings Summary
The drink deals at Duke's also land squarely in the 'meh' category, with an average of 18% savings on 21 items. Many cocktails, such as the Cucumber Mojito or Sunny Slope Nectarine Mule, hover around a 20% discount. However, sparkling options like the Sparkling Rosé, JCB N°69 at 13% off, barely scratch the surface of a decent deal, making it hard to get excited.
