If you are coming to unload on Friday, they are requesting that we only park by the front entrance if we have something heavy, large, or otherwise cumbersome to carry. They have asked that if what you are unloading is heavy, large or cumbersome, park at the main entrance, unload your stuff, promptly go park your car, then come back and take care of any unfinished business. The concierge at South Side is apparently very busy on Friday nights.
If what you are bringing is not terribly heavy and/or cumbersome, you may search for parking on the street (at a meter) or in the parking lot (which is very crowded) or across the street at Sala, which is a restaurant that has changed names several times in as many years (Sala has a large parking lot).
For those of you who are directionally challenged like me, I suggest getting directions off of google maps. The address to South Side is:
1409 S. Lamar
Dallas, TX 75215
Here is a map of South Side's location relative to Downtown Dallas:

It's easiest to get to off of I-30.
Here's a map of the parking lots that are available for us to use. There's also metered parking along the street.

If you're coming to the reception on Saturday evening, the parking situation will be the same. Occasionally, South Side has valet parking, but not always and I don't know if it will be available to you on Saturday night or not. Please let us know if you have any questions! We're looking forward to seeing you all there!
