A growing number of establishments are offering their patrons kosher food items, gluten-free cuisine, organic foods and other specialized offerings. Individuals who are looking for establishments that offer kosher foods should be proactive; calling an establishment ahead of time or visiting the establishment's website can provide additional information about specific food offerings. Establishments that offer genuine kosher foods will often display certification stating that some or all of the menu items have been deemed kosher by an approved kashrut supervision agency or rabbi.
