Colmar is only 30mins away by train/ 50mins by coach so it’s worth a short visit! They also have a really high density of Michelin starred restaurants… It’s definitely worth a day trip.
I’ve taken a quote from this article:
“We chose Colmar for its geographical location, close to Germany and Switzerland, and for its cache,” explained Wang Tian, chef and producer. At this time, the Lavandières bistro in Colmar was converted into a gourmet Chinese restaurant.
Colmar does seem like a bit of an obscure choice though the first season was based on a lovely beach in Thailand
