CHICAGO -- The Chicago Cubs are in New York for Game 1 of the National League Championship Series.
They left Chicago Friday morning and got a practice in at Citi Field in Queens.
Saturday night's game starts at 7:07 p.m. with Jon Lester starting on the mound.
The Cubs were 7-0 against the Mets in the regular season. But those were close games early on in the season, and this is a different Mets team after it bolstered its offense at the trade deadline.
The series doesn't come to Chicago until Tuesday for Game 3.
But, the city is already working on security around Wrigley Field.
Alderman Tom Tunney put residents and businesses on notice about what to expect.
Parking will be banned on Racine, Sheffield, and Addison. Sheffield and Waveland will also be closed.
Fans are being urged to take public transportation, but also warned that some buses will be rerouted.
It's tradition that the mayors of both cities make a bet.
Mayor Rahm Emanuel tweeted New York Mayor Bill de Blasio, offering up Chicago-made products like Lagunitas Beer and Giordano's Pizza.
He added a little tough talk, reminding de Blasio that the Cubs beat the Cardinals in four games in the National League Division Series.
de Blasio has yet to respond.
New York's transit system wanted in on the action.
The MTA tweeted the CTA, offering up a slice of pizza to the winner.
The CTA upped the ante with a slice for every home run. Then, the CTA attached a Vine video of Kyle Schwarber's home run ball landing on the Budweiser sign at Wrigley Field in the 7th inning of the Cubs' Game 4 win in the NLDS.
The MTA accepted the bet, and told the CTA to "Get ready to deliver a lot of slices!"
