This iconic side dish is more than just a burger companion; it’s a culinary experience when done right. After digging through Yelp’s March 2025 reviews, we’ve rounded up the spots in Boulder that serve up onion rings worth raving about.

Let’s take a crunchy journey through town.

Jungle

You might not expect a tiki-themed cocktail bar to be home to one of Boulder’s favorite onion rings, but Jungle surprises in the best way. Known for their vibrant burgers and tropical vibes, Jungle’s onion rings have earned a loyal fanbase. One reviewer said it best: “I love the onion ring. I wish the pineapple was in a ring instead of…” That kind of passion says everything. With a trendy atmosphere and open until midnight, Jungle is the place for a fun night out—with onion rings as your go-to side.

The Parkway Cafe

Locals adore The Parkway Cafe for its laid-back brunch vibes, but their onion rings deserve their own spotlight. Yelp reviews call them “super tasty, super crunchy,” and the perfect side for their legendary Club sandwich. This cozy café may look unassuming, but it consistently delivers big flavor. If you’re an early riser with a craving for something golden and fried, Parkway’s rings are the breakfast hero you didn’t know you needed.

Dark Horse

A Boulder institution through and through, Dark Horse is the go-to dive for students, sports fans, and late-night snackers alike. Their onion rings are praised as “perfectly crispy” and a delicious match with their house sauces. Whether you’re catching a game or just hanging with friends, Dark Horse offers that satisfying crunch you’re after.

Snarfburger

Don’t let the fast-food label fool you—Snarfburger brings serious flavor. One Yelp reviewer dubbed them “the best commercial onion rings” they’d ever had, noting the onions are likely pre-cooked, creating a sweet, melt-in-your-mouth center surrounded by crisp batter. Quick, affordable, and addictive, these rings hit the mark every time.

West End Tavern

Known for BBQ and rooftop views, West End Tavern offers onion rings that some call solid, but not standout. One reviewer said they were “standard, nothing to rave about,” but if you’re already there for wings or brisket, they still satisfy that crispy craving alongside your entrée.

The Sink

An iconic Boulder spot with colorful walls and college-town charm, The Sink delivers onion rings that shine—especially when paired with their famous Breakfast Burger. Reviewers describe the combo as “so delicious,” and for good reason. With over 90 years of history, The Sink knows how to do comfort food right.

The Hungry Toad

Rounding out the list is The Hungry Toad, a British-style pub with warm service and great pub fare. Their onion rings are frequently paired with their veggie burger, creating a winning combo for meat-eaters and vegetarians alike. The rings here are crispy, flavorful, and served with a side of cozy charm.

Whether you’re downtown, on The Hill, or exploring North Boulder, crispy bliss is just around the corner.
