The range of 500 meters seems a bit difficult, but I know, I recommend it to you.

Go straight along the main entrance of the library to Hao San Street. There are many snack bars on Hao San Street.

There is also the main entrance (Youth Street) to the north, Cui Wen North Road to the east (or walk back after going down the stairs, and you can see the place to eat after passing the park! )
