Post it as a Facebook event too to get more attention if you want. I will invite others too. I'm not sure how big you want it. IT's good to have more than 3 or 4 people at these things to make it feel like more of an event. I have tried to get groups going in the past and have only gotten 4 people at most, meaning I decided not to do it again until I could figure out how to organize events better.
Also, that location chosen is near several train stops for those not wanting to drive. Parking isn't the easiest thing around there. I always have a bit of parking paranoia. I feel like I can't relax and enjoy myself at a lot of locations with tricky parking situations. I keep worrying that I might have done something wrong and am going to have my car stolen by a guy in a tow truck. Anyway, I have figured out that there is street parking almost always available on the bottom level of South Water Streeet. This is a 3 level street, and I don't think many people venture to the bottom level much.
