Asked if they had gf, they said «yes, for now.» So it seems the gf bread will be off their menu in the future. I was a bit sceptical as they use the same place to make gf as everything else, but the lady who prepared my food was very careful and told me she had put the dressing on the side, since they couldn’t guarantee that it hadn’t been cross contaminated. The sub was tasty and I didn’t get sick. Not sure I would order from them again though.
Wife has eaten here several times and has not yet gotten sick. There is a manager there who goes above and beyond making sure the work area is cleaned and workers are informed about taking precautions to avoid cross contact. Same work space and oven. They use Schar bread that is individually sealed. Since the GF bread is one size they weren't able to do the ring up the kids meal GF.
I love that they offer gluten-free rolls and my favorite is "The Engineer" hoagie sandwich with sautéed mushrooms and onions on top. If you are extremely sensitive, there may be CC issues since they make subs with gluten bread. But I have not had any problems at Firehouse Subs, and have eaten at many different ones, quite a few times.
