A nice brunch attire. More than just a t-shirt and shorts, but not business casual.
Yes! There is plenty of parking for each location. For the Lake House, there is a parking lot right next to the venue. For Open Road, park in the green parking garage at Reston Towne Center (it is right across the street from the distillery and free on the weekends).
There will be no transportation provided between the Lake House and Open Road. It is a short drive away and there are plenty of Ubers/Lyfts in the area. You can also carpool, but please drive responsibly. Apologies for any inconvenience.
