In short- noisy environment, greasy fare, over-priced and a guarantee that your clothes and hair will smell like smokey food for the rest of the day.
Marche, especially this location is not a place (note how I didn't use the word restaurant) to have a nice meal. I have been here many times over the last few years, most occasions for work lunches ranging from groups of 4 to groups of 10+ people. The staff here are sometimes nice but the more normal encounter is that they are frosty and unhelpful. This is not a restaurant and you should not expect any table service even though you will pay a mandatory tip if you dine-in. There is a service charge for dining in (12%) but you don't really get any kind of service at your table at all unless you count clearing your table after you've left.
Variety over quality. I will give them credit for having a good variety of different food stations, however, the food is not made very well. Nothing really stands out in a good way, though I have had several experiences where the food stood out in a bad way. The process of lining up and paying at the end of your meal is very time-consuming when you come anytime near peak lunch hour.
I never come here by choice.
