I've been to Piato Too (for coffee) and Piato (for lunch). Customer service isn't that great--but if you know what you want and just would like to order, pay, and get your food with minimal interaction then you're all set.
My boyfriend and I ordered lunch, me an individual pizza and him a cheeseburger. The woman taking our order asked if he wanted a side--he asked if it came with the meal and she said yes. Uhh...no. The side costs extra, as we discovered after taking a closer look at the prices on the menu. She didn't even hesitate to lie to us. Also, the "individual pizza" is actually just two slices of pizza. Not sure what's so difficult about having slices of pizza on the menu, instead of something so ambiguous and misleading. It's clear that the slices are pre-baked and they just add the toppings on and heat it up. Kind of lame but it wasn't terrible. My boyfriend didn't like the cheeseburger at all (he said it was completely flavorless) and the fries were barely warm.
I came here because I had a gift certificate, so I'm glad I only had to pay for one out of the two meals we got. I won't be back...it's just not worth it for mediocre food, and good luck getting a straight answer out of anyone who works there.
