Ultimately, this place isn’t about the burgers. It’s more about the shakes—specifically, the off-menu shake-of-the-month, which rotates among addictive flavors like double espresso and hot fudge (and less exciting flavors like caramel-pumpkin). As companions to those shakes, the burgers are perfectly nice. But no burger here can compete with the chicken sandwich, which is topped with a creamy avocado spread and sweet grilled onions.
