Burgers, fries, hot dogs, ice cream, custard, beer and wine, oh my! The Shake Shack has everything you need to fill up and cool off on a hot day. And best of all, dogs are allowed to share in the fun. Don't forget to order Fido the famous Pooch-ini -- vanilla custard smothered in peanut butter sauce and topped with biscuits. It's woof-tastic!
