The article recounts a review of Costa Coffee's Iced Strawberry Coconut Matcha drink, which is priced at £5.50. The reviewer expresses surprise that Costa has introduced a matcha drink, as it's not typically part of their menu. After tasting the drink, the reviewer feels that the company may have made a mistake in offering it, suggesting that they should have left it off the menu altogether.

The author shares their personal experience as a regular customer at Costa, noting that they earned a free drink from a loyalty program, which they chose to use on the Iced Strawberry Coconut Matcha. The reviewer emphasizes their disappointment with the drink, indicating that even at a lower price when using the free option, it did not meet their expectations. The review highlights the ongoing trend of coffee shops experimenting with various flavors and drinks, but not all new creations resonate with customers.

In conclusion, this review serves as a reminder that while innovation can bring excitement to coffee menus, not every new drink will succeed with customers. It underscores the subjective nature of taste and the increasing competition among coffee franchises to offer unique and trendy beverages, which can lead to mixed reactions from patrons.
