They don't have their own parking. It's expensive.
You would have to use public parking
There is a parking lot directly across the street from the restaurant. It is free after 5:00 pm and Sunday. If you get there around 5:15 - 5:30 pm you can usually find a space.
There is a parking garage nearby. If you have your handicap tag, show it to them and the parking will be free. Otherwise there are some street parking that are free or paid lots nearby.
Parking can be very tough. City parking is reliable but not as convenient. You might be able to pay to park at Columbian across the street.
