I saw Joe's Cable Car featured last night on Diners, Drive-ins and Dives. The burgers there looked really good, but it's a bit far from Union Square where we will be staying (without a car). Are there any places nearby that serve a great burger and fries, open late would be preferable since we will be arriving around 10:00 pm, on a Saturday night. However, if the burgers at Joe's are that good, I could be persuaded to make a taxi ride over for a late night meal. Thanks for your help.
