Not a gluten free kitchen.
I ate at Melt recently and I ordered a grilled cheese on gluten free bread. They don't have a dedicated area for grilling my sandwich and used the same utensils that they used with regular wheat bread. I wasn't too worried because although I have celiac I am not as sensitive as some are with slight cross contamination. I appreciated them not slicing my sandwich with the same knife that they use for other sandwiches and notifying me that their cheese sauce is made with flour so he wasn't going to put it on the sandwich. I did however get sick fairly quickly after eating my sandwich and won't be back unless I am certain they have a dedicated kitchen area.
Same surface cooking, so be warned! My main gripe with this place is they charge an extra .92¢ for GF bread but my grilled cheese sandwich was only slightly larger than 1/2 the size of my friend's regular sandwiches (which fill the box). It's not really a comparable swap at all, since you get charged more for less. I tried the tots, they were good as well.
Great service with what I would say was Super Forward Friendly attentive staff. I asked about GF bread, he said he could make any sandwich on GF bread. Accepted the long pause and questions I had. I said, "My need is an allergy, not a preference". He stopped the process, turned into the kitchen, gave instruction and followed up on it. The staff prepared the sandwich on a separate surface and used caution. In the space, a pure kitchen may not be possible. I ate, enjoyed and had no reaction to a chicken club sandwich. It was a knock out delicious sandwich. I had no reaction. Of course, I would recommend talking with them and make your own judgement. I'll go back again.
