My husband and I visit Costa's at London, White City, Westfield Shopping Centre on a regular basis. The staff are always extremely polite, helpful and friendly, especially staff who have served us for several years. However busy there is always a warm welcome.
The coffee is very good!!
Costa is a chain of Italian coffee shops offering coffee made the Italian way, slow roasted for 20 minutes for a fuller richer taste. Costa also offers a selection snacks and cakes.
