We just went today for the first time after seeing the reviews on this site and having followed their feed on Facebook for a while (knowing that they were going to be opening in the area and curious as to what they were about). They did not disappoint. My son who is gluten intolerant got a buffalo chicken sub on one of the gluten free buns that they carry (I believe they are Udi's brand that are available to the restaurant industry but sadly not available in stores yet). He was so happy to finally have a sub sandwich again!
I got the Sriracha sub that is one of their current featured subs on a regular bun (not GF) and it too was very good.
It did take an extra 4 to 5 minutes for our order as they assured us that they clean everything to ensure no cross contamination but it wasn't a big deal since we had time to wait.
Also, they feature Kettle brand potato chips and I believe most, if not all, are GF (my sea salt vinegar ones were).
We will definitely be back.
