Drive thru is 24 hours except late nights they're under staff which is really annoying because every time I come here around 11pm or later it always takes about 15-30 minutes to get my order. This has happened 3 times already, to the point where I just put my car on park and the car behind me would turn off their engine. Not sure why they only have 1 girl working at night, there's something wrong with that. Other than that my smoothie was great, just not happy with how slow the service is at night!
