Oh, how disappointing! There was a restaurant back in Rochester (where I lived for years), N.Y., that was an upscale fine-dining place. it was one of the only places where we had a crumb sweeper! Chair and napkin service for the ladies, cloth tablecloths, linen napkins, all the glasses and silverware one would need for a multi-course meal, etc. And the fresh flowers and candles. I don't know if still in business, but if it is, I suspect it may have gone the way of the place you describe.
My DH and I love to get dressed up to go out, but these days, we'd be so out of place. Business casual is about as dressy as we get now. At least we look like we're stopping for dinner on our way home from work.
I hear that Ruth's Chris Steakhouse requires either jackets or ties; sounds more "upscale" than many places. The nearest one to us is about 70 miles away, but I have a friend who lives the other side of the state, and the location is about halfway for both of us. We're trying to set up something to meet her and her husband for dinner there.
I learn something new every day, but not everyday!
I've learned to never trust spell-check or my phone's auto-fill feature.
