 Testimonial from an actual client. Some restrictions apply. For complete details, please visit OptimaTaxRelief.com. Starbucks is brewing up a new type of coffee cup. KCBS's Matt Bigler. At this Starbucks east of San Francisco, the plastic dome lids that usually top cold beverages are now white. This customer was happy to see the new compostable cups. I think that's a good idea. It's better for the environment. The change seems to be in accordance with the local anti-plastic ordinance. We are so excited about it.
