Safety 10011. Terra's Ice Cream, Coffee, & Sweets
A scoop of the homemade ice cream in a waffle cone, the thing a celiac almost never gets to say yes to, since the cones are baked gluten-free on site. The coffee and baked goods make it a full stop, not just dessert.
Terra's is a 100% gluten-free specialty shop, so the ice cream, the cones, the toppings, and the pastry case all come from the same safe setup. It's open daily near Tysons, which makes it the reliable after-dinner answer in Northern Virginia.
