I have some exciting news for Butte residents needing a GF pizza fix. My friend took her girls to Silver Bow Pizza Parlor in Butte and discovered they offer GF pizza crust. I don't know how it tastes or how careful they are with cross contamination so if you stop in be sure to give me a report.
Silver Bow Pizza Parlor also has games and a carousel to keep the kids entertained, sorf of like a Chuckee Cheese. It's located at 3500 Harrison Ave in Butte and you can call them at 406-494-2750.
