The acai mix tasted really artificial and sugary. It reminded me of the flavored syrups used to sweeten iced coffee, rather then tasting like fresh fruit. The fresh fruit on top helped balance that out. It was good, but not as good as the salad.
Verdict: Even though the acai bowl was more like ice cream than a traditional acai bowl, I was impressed with both new additions to the menu. Most inexpensive food courts and fast-food restaurants lack any satisfying vegan options, but Costco's al pastor salad tasted really fresh and had a lot of flavors that complemented each other. The acai bowl was a little too artificially sweet for my taste, but it definitely was a good treat for dessert. Both meals were completely filling, and they only cost $4.99 each.
