Highway 50 is sometimes considered the 50-yard line in the rivalry between the Bears and the Packers. Squatting at that spiritual midfield  if not exactly the geographical one  is the Brat Stop, a sprawling restaurant/bar/concert hall/cheese shop just off Interstate 94 at the edge of Kenosha, Wis.

The Bears and the Packers will play in the N.F.C. championship game in Chicago on Sunday. The only other time the teams met in the playoffs was in 1941.

“This is bigger than the Super Bowl,” said Gail Khayat, working behind the Brat Stop’s bar.

Two neon helmets lighted the bar’s back wall. One had the “C” of Chicago, the other the “G” of Green Bay. Between the two, only one opponent matters.
