The clatter of tumbling pins precipitate cheers over strikes and high scores in Roxbury Lanes & Casino’s bowling arena, and silent staring contests precede shouts of victory and wails of defeat in the venue’s daily poker tournaments. The tables feature many stripes of the classic card game, including Texas hold'em, four card, and pai gow, as well as double-deck blackjack. To refuel for further sporting, visitors retire to the built-in sports bar, where they chow down on new york strip steaks, custom burgers, and a full selection of breakfast eats in the comforting glow of flat-screen televisions and the bartender’s neon-rimmed glasses.
