it sucks. you're better off looking at the website. in fact i'll even give you the url www.southfork.com unless you have a lot of time on your hand and nothing else to do or are just a huge "Dallas" fan, skip it.
Unique Suggestions: if you have to go see it and you will be in plano,tx
(the suburb of dallas where southfork is actually located) maybe head to connemara conservancy. it's an especially great place if you are into the outdoors and want to get a taste of north texan landscape.
South Fork - fortunately as years go by this should get less attention. I will admit that back in 1990 I did drive all the way up an "under construction" I-75 to see this. Why I don't know. It was sold and last I knew was used for flea market. From Rags to Riches and back to Rags!
Unique Suggestions: If you do go to South Fork, then you are pretty close to the 121 freeway. Might as well go to this area and see the new shopping area.
Hard Rock Cafe in any city is a usual trap for Tourists where the food isn't that good and usually expensive. But its where we all feel the need to check these places out from city to city. The Dallas one and their food isn't too bad though.
Union Station - for anything other than catching trains. I saw an interior shot of a grandiose staircase and I decided to make a special visit to see this grand old station. While it has undergone a face-life outside, any 'grandiose' is sadly lacking and not worth a special visit. However you can go through the subway through to the Hyatt Hotel to go up Reunion Tower very easily.
Everyone wants to see Southfork, the ranch where the wildly popular soap Dallas was located. First of all, it's in Plano, not Dallas. Second, it's small and disappointing.
I also avoid the West End Historical District nightlife. It's OK for lunch, when local office workers jam its restaurants, but at night it's popular with teens from the 'burbs and is the opposite of cool.
