Okay girls, I finally figured out the details! I've made an appointment for five girls to get pedicures at Belle Spa and Nails on June 15th at 11am. I picked them because they have great reviews, and they're located right between the Brown and Red line in Gold Coast.
Let's meet up first at the Starbucks a few blocks away at Franklin and Chicago (right under the Brown line) at 10:15am so that we can introduce ourselves and get some caffeine.
The cost should be $35 for a pedicure, and I think they only take tips in cash so be sure bring some.
