Hungry? On a budget? We got you covered. Actually, Barrel Proof has you covered. The Mission District restaurant and bar combo has $2 pizza slices every Tuesday night from 5-11 p.m. You can choose between "New York style," thin crust, three cheese, or pepperoni, and sometimes other combos as well. They also have free pool (which can be hard to come by in this city!) and great music to listen to while you eat, drink, and play. Who can say no to $2 pizza slices?! Not us!
