Bozeman has more options for gluten free pizza crust and bread. It feels like such a boom and I'm a tad bit excited about it all.
First off is Audrey's Pizza Oven which now offers gluten free crust. It's not listed on the online menu yet but Nicole saw a sign in their window and I gave them a call. The crust comes prepackaged on a metal tray so it doesn't touch any surfaces. They also said they use clean utensils so it should be safe.
Great Harvest Bread Company now makes gluten free bread. I don't know what the availability and variety are like. Please note on their web page they state gluten "free" (that can scare a person a bit) and give the warning "Please note that we are a whole wheat bakery, therefore; this product is not recommended for customers with the serious autoimmune disorder, Celiac Disease, as it may contain trace amounts of whole wheat flour". This could be a legal cover their rear thing but it's something to be cautious about. If you do want to give them a try they make the bread on Tuesdays.
Last we have the Homepage Cafe that offers gluten free bread for their sandwiches.
If you have concerns about cross contamination, etc. please be sure to check with them at the time to see what their practices are. And if you happen to indulge at any of these places let me know how it goes.
