Sit-down burgers and a full bar by Gate B7
Near Gate B7 in SEA’s Main Terminal, Relish Burger Lounge fills the gap between fast food and a real restaurant. It’s a proper sit-down spot with table service and a full bar, not a grab-and-go counter. Burgers land in the mid-teens, and with fries you’re usually north of $20, so this is a committed meal, not a snack on the way to boarding.
Relish runs in Terminal B, post-security, and draws families and business travelers who want to park it for 45–60 minutes. Expect pub-style burgers, fries, and salads at a solid 4-star level on Google and Yelp. One reviewer calls it their “default SeaTac dinner,” mainly because they can eat at the bar and charge their phone at the same time.
The Port of Seattle lists Relish near Gate B7 as one of the main burger options at SEA, so it stays busy during departure banks. The bar is the move: you get the same menu, a full liquor lineup, and typically quicker attention. Regulars on Yelp explicitly say to sit at the bar if you have less than an hour before boarding.
Watch out for timing. Multiple reviews mention slow service and long waits when B concourse flights bunch up, with a few people cutting it close for boarding. Burgers plus fries with tax and tip often push past $20 per person, so this is a pricier sit-down than Wendy’s or McDonald’s elsewhere in the airport, but several reviewers say the burger quality matches the higher check.
Tip: If your flight out of B or C boards in under 50 minutes, grab a bar stool, order a burger and fries immediately, and pay as soon as your plate hits the table so you can walk straight to Gate B7 when you’re done.
