Austin Beer Garden Brewing Co. at 1305 W. Oltorf (right next to the train tracks).
One of their "by the slice" choices had also caught my eye, so I ordered it as well. This was venison, spinach, pesto, white bean, roasted tomato, roasted garlic, and ricotta. This one was amazing (not that the sausage was bad). The crust had just the right amount of crispness and chew, but the combination of toppings really made it. It had a richness from the venison without being gamy or overwhelming, and the remaining ingredients provided a terrifically contrasting texture in every bite.
Oh, and the beer was darn good, too. :-).
