Harry's is really very good. It isn't fancy. The steaks aren't those modern, high-end kind such as you get at Ruth's Chris. I would describe everything about it (the decor, the service, the menu, the style of preparation of the steaks, the selection of sides) as a throw-back to the 1970s. And that's a good thing! No cold, loud, granite tables. No hip waiters muttering about cage-free poultry. The prices are reasonable. The service is comfortable. It doesn't push the envelop on creativity or sophistication. You can definitely come as you are (maybe to a fault?). I wouldn't call it gourmet, but it is very, very good.
P.S. The fish and burgers and pork chops are good, too.
