When I went here they had no Gf buns so I can't comment on how good or bad they are but you can order without a bun. I got the corned beef with Swiss cheese with no bun and it was very good, not all of the sides are gf but they do have chips which are substitutable. They likely have some others that I didn't ask about so in the future if/when I come back again I'll see if anything else is gf for the sides.
