Strawberry banana smoothie cup from Cowboba. I forgot to take a photo of the sign, darn it. They specialize in American steak and Vietnamese bubble tea ("boba tea") and smoothies.
I've never seen this method of sealing drinks before. I think it may be a little "greener" than the usual snap-on lid, since it uses less plastic. They make the drink, then seal this plastic cover on (using heat?). The straws are cut so they have a sharp point you poke through the plastic.
