"Insomnia Cookies operates both a bakery and a delivery service, which will bring still-warm cookies to your door until 3 a.m. The menu will remain the same as other locations, with 12 flavors of cookies (think chocolate chunk, s’mores, peanut butter chip), which can be made into ice cream sandwiches, brownies, and cakes. It also serves milk. Insomnia’s Austin retail hours are from 11 a.m. to 3 a.m. weekends, and 9 a.m. to 3 a.m. weekdays. Delivery hours are from noon to 3 a.m. weekends, and then 10 a.m. to 3 a.m. weekdays. Insomnia was started in a college dorm room at the University of Pennsylvania and has expanded to over 100 stores nationwide, including one in San Marcos." - Erin Russell
