This is the departure station of Eurostar Paris and the train departure station of Paris to many other places. The station is open. Besides Eurostar, all the other trains look at the big screen on the first floor to find the platform. Eurostar checks tickets on the second floor (the first floor of Paris), checks security, passes customs, has a special waiting room, which has shops, coffee bars, in good order. But if you take the train to the North Station and then go out for a taxi, be careful. Don't believe any "cattle" who chat with you. Be sure to line up in a special place along the instructions (the signs in Paris have Chinese). But even if you are in line for taxis, be careful not to be dragged into the black car by non-staff members. Because people who have just arrived in Paris may not be able to tell which is the station staff and which is not, and those cattle are particularly fond of looking for Asian faces to start with. Keep in mind that taxis are timed, the starting fee is only more than 2 euros, from North Station taxi to Charles de Gaulle Airport is almost 50 euros, to the urban area is absolute. No more than 30 Euros, even in traffic jams. So if the driver doesn't make a direct quotation without making a watch, and the quotation is 80 Euros and 90 Euros, get off immediately.
