I've been to the Wexford location many, many times and every once in awhile I get glutened. I've managed to wave away most of those times, but recently had an experience where I was just immediately and undoubtedly glutened. It's a shame, their waffles are very tasty.
(For other allergens, too, they're somewhat lax, so if you have something other than gluten issues you'll have to be careful with those, too)
