Call and ask? (Not meaning it rude lol)
There's plenty on the menu without gluten, though they don't specifically have a gluten-free menu. Mention it to your server when you order as you would any allergy and they should be able to substitute anything of concern! http://joeysdiner.com/menu.html
Sorry, No. Great desserts though.
No reservations. Just walk in and the host will seat you. I've never waited longer than 5 minutes, it that.
