This is an amazing place to bring a friend and catch up for hours, yes I said hours. One time me and friend who hadn't been in touch for a 2 years sat here for 4 or 5 hours! The place was really busy but we were under no pressure by the staff to leave. Also it is a really nice atmosphere, and really nice for people watching as well.
I like most of the food and drink options here. I have tried a good amount of the paninis and smoothies, all are good and worth the money. The only thing I would say is for people that haven't been to Lettieri is that there are a lot of options for the smoothies on the board, but if you go in the dead of winter, you are only going to get one with more "seasonal" and non special fruits like apples, oranges, bananas etc.
