I visited Sundae Drive for the first time yesterday and while it was a good drive for me, it was absolutely worth it for the treasure trove of nondairy soft serve flavors and gluten free cones with no upcharge! This is the first ice cream place in NH that I've encountered with gluten free ice cream cones and that suprise made my ice cream even more enjoyable. I've been dairy free for a long time but have never stumbled upon any of their flavors, let alone this many soft serve options! For you hard ice cream lovers, they do have a smaller menu of hard serve options. I indulged in a small cotton candy nondairy soft serve and absolutely loved it! I'll be back sometime soon :) the prices were also very reasonable for this level of speciality ice cream.
