A boutique is a small, specialized shop that deals with a limited clientele and offers a limited product line. It stands in contrast to larger retail establishments like department stores, supermarkets, or warehouse clubs, which offer a wide array of products or services. The term can also apply to small, specialized brokerage firms as compared to financial supermarkets.
A supermarket is a large self-service retail store offering a variety of food and household products, organized into aisles and often operating on a cash-and-carry basis.
