Very poor customer service. I ordered small frappe which was under five dollars. I give my credit card and get "Oh, I have to charge you 50 cents to using a credit card under 5 dollars" from cashier. But there's no sign notifying customers about that. It's a lunch time, I am with friends and in a rush, so I am more collaborative and I ask if larger frappe will cost more than five dollars. He says, "It's $4.75. Then I am going to charge you 25 cents". So this is just a subjective bullshit he's pulling out. I call it an unacceptably bad customer service.
On the frappe quality: it was highly unremarkable. Lots of ice.
They call in the mic your number if it's ready and repeat it multiple times. Very annoying.
I really wanted to stop by some other time to try their sandwiches, but I lost the desire after such treatment.
