Poland's number one coffee chain's Altus Centre offering is small and pleasant. Arguably the best coffee in the country (maybe the most expensive as well), plus a limited selection of sandwiches, wraps and cakes. Also at ul. Mickiewicza 22 and Silesia City Centre, ul. Chorzowska 107. Depending whichever you choose to go to, be sure to check www.costacoffee.pl for various opening hours.
