I was here for the free drink (Feb 20-26 from 12-1pm). The service was excellent - the staff was very polite! That day's free drink was mixed berry yogurt but they ran out so we got the watermelon juice as a replacement. They used fresh watermelon and it tasted absolutely amazing! I would definitely recommend coming here if you wanted a refreshing drink. However, it is a little pricier in my opinion for some of their drinks - the prices range from around $3 to $7.
As a side note- the logo is really cute!
