Vapiano serves overall good food that is made right in front of you. After you slide the card, you can basically awkwardly watch them cook your food; this is the time to ask for additional stuff or to make sure to leave out stuff. I have noticed that certain cooks tend to be more above-and-beyond than others, while some may have an off day and your food could be just better; so its best if you frequent here to get to know the cook a little bit to improve your food.
Generally, the pasta is pretty good, though I wasn't that happy with the calzone I got once (was cold inside, while hot outside). During lunch time it can get really busy as people wait in line to be served; the bar area is mostly empty at this time, plenty of seating. Televisions are the bar area usually on sports. Pay as you leave with the card you used to order your meal; the price tag is higher than average lunch fair, so spend accordingly. Overall, it's okay... as some failings that can be better, but still worth a go.
