In honor of their new 40-day dry-aged hamburger, Primehouse in Chicago is selling the normally $15 burger for only $5 this week. Phil Vettel of Chicago Tribune's food blog The Stew reports that the "seriously good" half-pound burger is topped with garlic spinach and fried onions on a potato bun with smoked-bacon mayonnaise. The burger is only available at lunch (11:30 a.m. to 3 p.m.) until Friday, so Chicagoans, get your burger now!
