Grand slam at NYC Denny’s

Denny’s wants to open its first New York City restaurant in a 23-story luxury condo building downtown — and some tenants are incensed.

The discount diner chain, known for its “Grand Slam” breakfast, is angling to take up space at landmarked 150 Nassau St., across from City Hall.

Apartment owners are furious that the chain, known for its cheap menu and round-the-clock service, wants to share their posh address.

“Residents are really concerned that the value of their investments will go down,” said a building employee.

The closest Denny’s is in Englewood, NJ.
