"Delicious Hole Foods at the Jersey Shore!" While we have not yet been ourselves, this donut shop has 4.5 stars on Yelp.
While not a boardwalk in the rides and games sense, this is a great spot for a walk by the beach. While described as "breathtaking", "beautiful", and "relaxing", Cosmopolitan569074 on TripAdvisor did complain that the cafe near the boardwalk was "the most disgusting eatery that my husband & i had been to", so maybe avoid that.
If you prefer lakes over oceans, this park is located approximately 2 blocks from the Boardwalk and has a picturesque lake with a popular photo-op bridge.
