Today's Challenge:Favorite Regional Speciality This was an easy one.I have not been to Katz's Deli many times but the few times I've gone I've left pleasantly stuffed and surprised by how fresh the meats are and how low key the restaurant is.Being that the restaurant is famously known and opened in 1888, I expect this restaurant to be a bit high class because so many celebrities.But it's not. It's super chill. It's totally diner style but they offer some of the best meats I've had in this city.With diner style seating and tons of celeb photos plastered on the walls this place screams old school New York.If you eat meat and are in New York City, you have try the roast beef. Just look at that photo above.It's a dream to eat.
