Some other options a little north:
Delilah's - upstairs might be a little better for networking. No food, AFAIK.
Sheffield's - back room has a bar and they have food - there is a beer garden when it is not fall/winter.
Not far from Hop Haus:
Fado - they have an upstairs that might be good, also a middle tier area that could fit. they have food.
English - multi-level and food, might be a little loud, never been there on a thursday.
Loop:
Tilted Kilt - heard good things about this place, but it might have nothing to do with food or drink
Sweetwater - saw a review of this place that was good, so photos look like it might be more open for networking
Elephant & Castle(s) - there are a bunch of these sprinkled in the loop
