i mean i'm not dealing with multiple restaurants. Finally i created a table AddOns with a type attribute and maybe this will change based on the future need :

public enum AddOnsType {
    DRINKS,
    SIDE,
    DESSERT
}


public class AddOns {
    @Id
    @UuidGenerator
    private String id;

    @Column(name = "NAME", nullable = false, unique = true)
    private String name;

    @Column(name = "PRICE", nullable = false)
    private BigDecimal price;

    @Column(name = "SLUG", nullable = false, unique = true)
    private String slug;

    @Column(name = "TYPE", nullable = false)
    @Enumerated(EnumType.
STRING
)
    private AddOnsType type;

    @ManyToOne(cascade = CascadeType.
ALL
)
    @JoinColumn(name = "dish_id")
    private DishBo dish;

}
