Yes, its a bit slower for gf ice cream but we've never had a problem with them going out back and scooping with a clean scoop and have never gotten sick. So 5 stars for ice cream. Limited options at grill shack in Westford but they do have a few options for celiacs at corporate/ group events.
Celiac? Be prepared to pour over a long list, when they find it, and then wait an extra 10 minutes or so for clean scoops, etc. On the restaurant side, selection is thin at best for GF folks. This place is a gem, and we do wait, but it ain't exactly celiac friendly.
They have a list of flavors that are gluten free...I went here last year and got a clean scoop from a new container of ice cream (and it was delicious and I didn't get sick). However...I went this year and I was told that they do not normally clean scoops between different types of ice cream. They will clean scoops if asked for allergies but they wouldn't scoop from a new bucket. No point in cleaning the scoop if the ice cream is potentially already contaminated. Not celiac friendly.
I had an awesome experience in their cafe yesterday! I was poking around the store and saw that they had GF cookies. I asked the very friendly people behind the counter if they were cooked separately from regular cookies and they told me all about their GF preparation. For example, for breakfast and lunch sandwiches, they have a separate toaster, separate cutting boards, they change gloves, etc. I was very pleasantly surprised because I wasn’t expecting to be able to eat there- just figured I would sit while my friends got food from the grill outside. I ended up getting a Turkey BLT on GF bread and it was delicious! The workers were awesome at their explanation of their kitchen procedures and knew all about cross contamination, so I felt safe eating there. (This coming from someone who is super sensitive).
