This fixture of the Tributary Brewing Company parking lot serves up a rotating menu of sliders, including the Big Belle, a two-patty ground beef brisket burger with lettuce, tomato, American cheese, and Thousand Island dressing. The local take on a Big Mac hits all the right nostalgic notes with the same amount of mess but better ingredients.

Reviving a beloved neighborhood bar isn't easy, but Mike Fraser and his team have done a great job honoring the past while putting their own modern touches on the underground space. The menu is a perfect example, showcasing familiar yet decadent dishes like the Archer Angus beef burger with bacon ground directly into the patty.

In their previous roles as owners of Small Axe Truck, chefs Karl Deuben and Bill Leavy wowed Portland with their cold-smoked burger. Naturally, the signature dish survived the transition from Small Axe to the new East Ender, which the duo reopened in March. For $14 at lunch, the latest iteration of the evolving burger is topped with Stilton and caramelized onions, with a side of greens and tempura onion rings.

Nosh's Apocalypse Now Burger put the eatery on the map, but its kitchen never stops coming up with absurd ways to fill your belly. Case in point: the $12 Slab Burger, which uses the signature dish from sister restaurant Slab — enormous, billowy Sicilian-style slabs of pizza — as the buns, along with sharp Provolone, cherry pepper sauce, and basil pesto. Godspeed, intrepid eater.

Reopened after years of planning, Rudy's has stepped up its food game. The burger reflects that: it's $14 for house-ground beef with kidney fat cooked to 125 degrees in a CVAP (controlled vapor) oven, which is like a bagless sous vide technique. Topped with local bacon, cheddar, lettuce, tomato, and caramelized onions, served with parmesan fries. Quinoa or turkey burgers are also available for those craving something less beefy.

A local restaurant that feels like a chain, Thurston's offers the "have it your way" approach that many burger fans crave. Build your own with free toppings like sauerkraut and sauteed mushrooms, or get the Thurston Burger with cheddar cheese sauce, grilled onions, applewood smoked bacon, and zesty house sauce, all for $6.50. Don't be surprised if you see Thurston's franchising the concept within a few years.
