This Whole Foods is the only one, for now, in Portland, Maine, so it makes sense that it is so large. The place is packed so full of produce and local produce when possible, that I feel that it's produce section is the largest I have seen in any other Whole Foods market. The layout is very spacious, so that may be part of it. However, any vegetable or fruit you have ever found at a Whole Foods is here.
There is also a respectable bulk foods section, and very conveniently, it is right by the produce section. Plenty of herbs and spices can be purchased in bulk, as can coffee. They have many fresh juices available for purchase in the produce area.
Great assortment of vegan frozen desserts and prepared foods (i.e. fake meat) if that's your predilection or two. Good selection of refrigerated non-dairy milks, but the shelf-stable non-dairy milk selection is even better. Good selection of raw snacks, as well as regular dried fruit and raw nuts.
Beautiful selection of prepared on-site cooked foods and salad bar vegetables. It is generally by weight, so be careful as you load up your plate. Pre-made on-site baked goods like cookies, scones and cake slices have vegan choices, which is nice - none are yet gluten-free also.
Broad array of beer and wine for the connoisseur, enthusiast and fan of such libations.
As a veg*n in Portland, this is a saving grace that is more reasonable and affordable than dining out every day.
Cons: Needs gluten free and vegan cake!
