Is there any nice restaurants to go eat around there ? What’s th best option?

There are nice restaurants on Flatbush on the other side of empire Blvd going towards Lincoln Rd and beyond (not sure what's north or south)

Not much close to the Zoo. If you head up towards the Museum/Library, there are nicer restaurants Washington Ave and Vanderbilt Ave or farther over into Park Slope.

Nice restaurants within walking distance of the zoo.

I am unsure of that, Just more of the same old same old.

No. Just fast food restaurants

McDonald's

Mostly fast food down the street - Dunkin, Popeye's, Wendy's... The usual
