So... if you'd like to figure out (before heading out for the evening) if your destination is 51% posted or not, you no longer have to call and query the staff at the establishment in question. Go to:
http://www.tabc.state.tx.us/" onclick="window.open(this.href);return false;
And click the link, 'Public Inquiry'

In the resulting webpage, click the first link, 'Verify the status and other information...'

Now fill in as much of the next form as you think is needed. I was impressed that as little as the 'trade name', street name (not the entire street address, even) and city were required to get the record I was looking for.

And finally, the results! I highlighted in yellow the new field they've added to this page. RED means it's a 51% business, 'BLUE' means you're good to carry.
