I've been to The LooP a few times now, and I really like the place - it's perfect for an easy breakfast/lunch. The coffee is good (they do delicious cappuccinos, lattes as well as heavier drinks like the tiramisu shake). The sandwiches and salads are nice too. I particularly enjoy the Chicken Caesar salad and the chicken chipotle sandwich. Both were great and reasonably priced.
The seating is a bit limited for groups of 3+, as it's mostly 2-seater tables. I've been with a group of four before, and we had to just wait for the guests at the communal table/bench to leave.
They also sell espresso machines- not sure why, but they do.
Overall, I've always had a nice experience there. I would only suggest that they reconsider the seating options.
