Due to the nature of the license, they're only allowed to serve beer, wine, and wine coolers. Back when I was ordering manager, we had many fine brews on tap, such as Guinness and Bass (or was it Harp?). The Guinness had nitrogen, which was even kept at the appropriate temperature. We'd be a bit more experimental with the bottles, ordering whatever people wanted and promised to drink.
Last time I was in the Pub, I saw that the food was the same as when I worked there. Chips, pretzels, popcorn, and the usual bar snack fare.
