Also get ahold of Blake who owns Joe Mommas

El Guapo's Cantina, Tulsa, Oklahoma
If not try to get ahold of Michael Sager, he owns several of the old warehouse type buildings in the area.
One of my best friends had his wedding reception at Lolas. Is a great, laid back, atmosphere.
Lola's at the Bowery Rebecca Ungerman plays there often and she would be great for some live music if you wanted that.
