It was kinda hard for me to decide - they're all real sharp looking! I guess it really depends how much you want the "wine theme" and the word "Bistro" included.... if that's very important, then I like #4 over #3. The only minor thing I see with those is the "DC" itself, I understand that it stands for DC in DeCarlo - but you have Club DeCarlo at the top - so it almost feels like you should have it be CDC or CD, but DC fits fine.
Now for #1, I finally made a connection - Club DeCarlo at the top and the "DC" over the "Club".... for the "Club DeCarlo" very nice!!! I was wondering at first why it wasn't a spade.

My pick would be #1, but it's seems obvious that wine is a big deal and likely important to your theme - so I suggest that you replace "Tyler, Texas" with "Wine Bar & Poker Emporium" at the bottom of #1 and see how that looks. It might be a nice match - maybe the best of both worlds? Other than that, I see it as a personal choice - because they are all very nice and I don't know you personally.
Very nice work - good luck and enjoy.
