Shops in the 'supermarket' category all have similar layouts and operations but may vary in their offering to the customer. Most will have a convenience kiosk, produce, meat, fish, groceries and frozen food, and manned and self-service checkouts. However depending on the size of the shop they may also have an in-shop bakery, butcher, fishmonger, delicatessen and pizza counters, a cafe, TU clothing, general merchandise, petrol station and online picking department. Some shops also feature concessions such as a beauty hall, travel agents, Jessops, Patisserie Valerie, Specsavers, Carte D'or and Ben and Jerrys ice cream stands, Zizzi pizza counters, Sushi Gourmet counters, juice bars, The Fragrance Shop, Argos and Habitat. Others also feature a "Centre for Dentistry" where dental treatments are offered and/or an "Explore Learning" centre where children are offered extra English and maths tuition. Some shops also feature a Starbucks Coffee instead of an in-shop cafe.
