King Kullen is a clean, local supermarket with good selection and decent prices, especially for the Hamptons. It offers convenient services like an online ordering system with knowledgeable staff who assist with substitutions, and a friendly delivery driver. The store features a dry cleaner at the front and a busy bottle room, along with a coin star that often breaks due to heavy use. Staff are friendly and helpful, making shopping a positive experience. Although some find it a little overpriced, many appreciate its wide selection, 24/7 hours, and nostalgic feel as a place they have trusted since childhood.
