It's a decent variety of gluten-free items, which is great (including some things I've never seen elsewhere, like GF perogies!) but it's REALLY overpriced. For instance, a 4-pack of Udi bagels is 8.99 here, vs. 5.99 at Sobey's or Metro. They have some items made fresh on-site, but they're also quite expensive. One nice thing is they have many baked goods, etc. available for order, so for someone who needs to order a cake or meal and be guaranteed it's gluten-free, it might be worth it.
There's a good amount of parking in the area, though the storefront is a little obscured and it can be easy to miss.
