I got lunch in two parts, first a beer, which I balanced with a giant tub of popcorn (O.’s lunch) while I carried a burger and fries in a wobbly way walking in front of us. Then O. had to go to the bathroom so I took him and got myself a cheese quesadilla. There’s a Calexico in the Barclays Center but all they sell are fish tacos, nachos, and a cheese quesadilla. The latter was the best option.
