I love Copabanana on 4th and South Streets in Philadelphia. The burgers are my favorite. You can order one with a dozens of toppings to choose from. If you order it rare - it comes rare!! And they have Copa fries - curly fries cooked with jalepenos and onions - to die for!! Copa burgers are HUGE - they come on a kaiser roll!!! Don't order any appetizers unless you only plan to eat half your burger. And one order of Copa fries can easily be shared by two people. Staff is typical South Street style - lots of piercings, tattoos, colorful hair and semi friendly. Once you get your food, they leave you alone to enjoy!! I like that. The beer selection is pretty good. By the way - burgers are half price on Wednesdays during lunch hours!! The University City location is alright - but slow on service. The 15th street location, if still open, I only frequented for frozen margaritas years ago when I worked at Magnolia Cafe on 16th and Spruce, which is now Los Catrines Tequila's (Great place), that used to be on Spruce between 15th and Broad. Anybody remember that?
