Probably the nicest building downtown. The RJC or Regional Justice Center houses the Muni, Justice, and District court. Since there's so many bad drivers, people who may have violated any law, or settle a civil claim the RJC is always busy. There are at least two entrances but it seems the line is the longest on the Lewis Street side.
But I came here recently, did my thing, and left. You can always count on the food stand like that hot dog on the corner or food truck waiting outside to fill you up.
The RJC also provides interpreters, every case, and attorneys if you can't afford one, not every case. There are ample security and court Marshals to provide additional assistance to go along with the front counter information booth.
