I've ordered via app and eaten here on person a few times since my diagnosis and haven't had an issue. Their menu markings are a bit odd in that the main meal items that are already gluten free do not have the mark for "can be made gluten free" even though the sides are usually pancakes or toast. This makes options that are normally safe (bacon and eggs, Northwoods hash browns, corned beef hash) look like they aren't safe for some reason. GF food comes out on solid colored plates and the servers are great to work with.
