Come to see the beautiful building (be sure to check out the lobby of the attached Hyatt - ask about the Whispering Arch!), or for dinner at Landry's, or the tasty Key Lime Pie at the Key West Cafe, or to feed the enormous goldfish in the pond behind the mall. Just don't come to shop, unless you're a connoisseur of those cheap, cheesy, touristy t-shirts. No shortage of those here, for sure. Check out the entertainment of the chanting fudge-makers at the Fudgery, as they get the whole crowd involved. In short, stop by for a quick look at Union Station, but I wouldn't allot more than an hour for the entire experience.
