Starbucks is offering a 'for here' option for customers to enjoy drinks in stores in reusable mugs, as well as free refills in stores for hot or iced coffee and tea.

Starbucks fans can now get free refills for some drinks — but not all. The coffee chain is also bringing back its self-serve milk and sweeteners bar.

Starbucks is bringing back free refills and a condiment station, but there are few rules to be able to use these services.
