It is a great branch of Costa. There are other branches of Costa in Kingston too but, for the taste of coffee, I think this is probably the best one and they might want to consider sending their baristas to other branches for training purposes so that other branches can catch up :) It is usually a cosy place too but occasionally they seem to turn on the air-conditioning a little too much given that the temperature outside is already low enough. The staff members are all kind and friendly. There are plenty of seats both inside and outside. It is also quite fun to spend time in the seat outside as you can enjoy the view of the whole Bentall. A flat white and a large latte are my personal favourite. If you want a generous amount of coffee/caffein, nothing beats a Costa large (latte/cappuccino) and a picture has been attached for this 😎 That said, I am currently not a great fan of decaf coffee at Costa as the taste does not seem to match that of the normal/caf coffee. I hope they improve on their decaf soon which will make it even better!
