"This is the original location of the famed Austin-born Texas burger chain, with stacked burgers (duh) and milkshakes (flavors range from double chocolate, vanilla, and root beer to Oreo) available in the Zilker neighborhood. Takeout orders can be placed in person through the drive-thru or walk-up window; takeout orders can also be placed online. The outdoor dine-in areas are surprisingly romantic, with robin egg blue picnic tables under string lights." - Nadia Chaudhury
