@clmsoup - that's very generous of you to offer to host, and if that's what the group comes to a consensus on, we'll be there.
My personal preference would be a location a bit more central (bike accessible) and outdoors, if the weather cooperates. Mueller has some nice grassy (and shady) areas where we've met up with another group. Throw frisbees, picnic, discreetly enjoy beverages; playground nearby. Here's the spot I'm thinking of: https://goo.gl/SVimcl
Another option across the road is Patterson Park. Or Zilker, but parking can be a bit difficult there for those driving.
Saturday Feb. 4 would work for us.
How about Thursday February 2 or Saturday February 4?
I'm happy to host a get-together at my house (near Mopac and 183).
Or Genuine Joe's has a comfy meeting room with minimum tab per hour:
