it's company policy to keep the bread products away from the burger fillings, so the risk of cross-contamination is incredibly low by default. I've been there several times and I've never had a problem. the staff were knowledgeable and immediately checked in the back when they couldn't tell me something for certain.
it's my current favorite place to eat out, i actively annoy my family by pointing them out when we pass by. i always get the Delux Butter Burger and either the broccoli or fries, which are made in a dedicated fryer. I'm *very* picky about my burgers and i love it, they even sub out the raw onions for grilled when i ask. the burger comes in 2 containers, the meat/filling and a bun in a bag, so some assembly is required. the only thing i wouldn't recommend is the mint ice cream as it is a bit toothpaste-y, which is saying something coming from me. however, the ice cream itself is good and I've had no problem with the other GF flavors.
if you do decide to go to this location, i recommend you avoid Cypress Gardens Boulevard until the last possible moment as it's a magnet for crashes and reckless driving.
