Zagat
Houstonians are crazy about the In Queso Emergency Kenny & Ziggy's.
This year, close to 3,500 Zagat users and self-proclaimed burger aficionados visited the restaurant-rating website to review the top hamburgers in 16 major cities across North America.
In order to come up with the "Overall" score, participants rated their city's most popular burgers on flavor, ingredients and value. The scores are based on Zagat's 30-point scale.
