I have been to Marche a few times over the years. As many other reviewers mentioned the great thing about Marche is the variety which is great if you're going out with a big group (or small) and no one knows what kind of food they want until they see it. The restaurant is essentially like a fancy food court. They use a card system that everyone gets a expense card which get swiped when you order and you pay at the exit (another convenience if you're going out with a group). I wouldn't call the food extra ordinary good but it is pretty decent for the variety they offer. A favorite station for me is always the Rosti which is i guess a swiss version of hash brown. You can never really go wrong with fried potato. There are also a couple of bars that you can order alcohol. The night we went they were very busy and there was a lot of smoke from different food stations. They offer different sitting areas and rooms with different atmospheres. Overall, i think they are still a pretty unique option for dining.
On a different note, the men's bathroom was very messy and there was no soap or paper towels anywhere. Again maybe because they were really busy that night.
Food: 3/5
Price: 4/5
Service and atmosphere: 3.5/5
Overall: 3.5/5
