The only place I know of that has a parking lot is Spaghetti Factory, and they probably wouldn't let us park for longer than just dinnertime.
I think most of them are not more than a couple of blocks further than Ivar's from the concert hall, except for Spaghetti Factory, Anthony's, and 6-7. Would we want to park near Benaroya and then walk to the restaurant?
Well, either just parking once, or parking at a restaurant with good parking, was my goal. There is good parking at Benaroya. That's not the problem at all :~D
