Found Hawk's in the SE parking lot outside of Jerry's Bar (6301 Military Ave) just north of Infusion Brewing Co. in Benson. Their main attraction is their spent grain pizzas, which I ordered two slices, the first was their Carnivore's Delight (Beef, Sausage, Pepperoni and Bacon) which came in a very generous slice, and was quite good for a midnight snack. The second I had was their That's Amore (White sauce, Chicken, Bacon, Green Peppers, and Tomatoes) which was alright, but nothing special. The crusts tended to end up to be more like hard crackers, but I would suspect that is what becomes of spent grain.
As with most Food Trucks you will have to find their Facebook page to see where and when they will be. This weekend their schedule looked like this:
Friday 9/26 9-close Jerry's Bar
Saturday 9/27 7-close Library Pub
Friday 10/3 9-close Jerry's Bar
Saturday 10/4 12-3pm Paradigm Gardens
Saturday 10/4 6-close Library Pub
Sunday 10/5 12-3pm Paradigm Gardens
Tuesday 10/7 5-9ish Crescent Moon Ale House
They are worth a try to see if they hit your bill!
