If I had to study, have a coffee or tea with a friend to talk or get light breakfast, Panera would be my go to spot.
First, if you have not tried their breakfast soufflés, you are missing out. These flakey, savory breakfast quiches are sitting on a warmer so it comes out warm. The cheese, egg and base are so well put together, it doesn't matter which one you order. They are all amazing. Salads are good too.
Next about Panera, they have comfy booths for 2-4 people to sit in. These are good to have good conversation with friends and to study. Some of them have outlets on the wall so you can plug your devices in. I'm also pretty sure they have free wifi.
