Tightly packed shelves and VERY narrow aisles make for an interesting manoeuvring experience through the store, but once you find your groove you'll come across many things that you 'need' to buy, including my favourite protein powder of all time, the ever elusive Spirutein. Although they don't carry all of the flavours available in the U.S., they have the standard vanilla, chocolate and strawberry and the prices are reasonable. Hey, Canadians like peanut butter & chocolate just as much as Americans so I don't know why distribution comes to a halt north of the 49th parallel.
They also have a ridiculous amount of Greens Plus products and the staff profess to be experts on the topic - I chatted with the owner briefly and he seemed very knowledgeable about it. Friendly and polite fellow who was very open to new ideas on products to order.
