I ordered from Insomnia cookies on my senior year of college at Penn. It sounded good enough: order cookies and they'll be delivered warm to your dorm room. It wasn't just good though, it was amazing! They have super fast delivery, their specials are great (a pint of Ben & Jerry's Ice Cream with your order!), and their toppings are to die for (twix, milky way, etc...and they can add them to their brownies and blondies too!).
This service was started by two Penn Students in or about 2003. They start at 9pm and close at 3am. You can order cookies, brownies, ice cream, milk, blondies and more. You can choose from many traditional toppings (chocolate chips, nuts, etc) to more non-tradiational toppings (like milky way, snickers, peanut butter chips, etc). They are very friendly and their delivery is very prompt.
So, late at night and craving a sweet treat? Then Insomnia Cookies is the place for you.
