The food at Aldo's is excellent. There are always good vegetarian options available, and it is conveniently located on campus. The lines, however, are very long. The service is the reason I rated it as a two.
Once, I ordered a chai latte, was charged for the drink and then proceeded to wait 20 minutes for my order. When it still hadn't come out, I asked the cashier when I would get my chai. She responded that they were out of chai! So I wasted my 20 minutes only to have them try to figure out the register system to refund me. They ended up giving me a free beverage on them. When I went next time to use this beverage, they had mysteriously run out of coffee lids so I couldn't take my coffee with me! I think if they get their act together they could be amazingly successful!
