Union Station will probably never be as famous as Grand Central Station in NYC, but it's our own landmark train station. Now that the MetroLink and MTA are making good use of it, improving it's look and upgrading the local transit system, Union Station has become a NEW landmark. More people travel through there than ever before. I think if they added a couple more restaurants, even a fast food place or two, it would become an even bigger highlight of downtown.
Pros: history, conveniently located
Cons: crowded at rush times
