The premise of Babel is to gather people from all over the world in a casual and fun environment to practice different languages. If you didn't come last time, don't worry about it. You always have a chance to come in and mingle, grab something to eat or drink and learn a new language! It's a great opportunity to meet new people, share some experiences from home and brush up on a second language in a supportive environment. You don't need to sign up or know any particular language to come--just come with an open mind.
