Hi Molly,
Here is a few places where I went when I was in Paris last year in February. Also if you want to add things to the list you can create a 4sq account and add me.
Place Charles de Gaulle (Avenue des Champs-Élysées), Parigi, Île-de-France
Monumento · Chaillot · 798 consigli e recensioni
Michael Easterbrook: Not sure if it is open to US residents, but when I went under 25's got in free to loads of tourist places such as this place. You just bring your passport or driving license and they give you a ticket
271 boulevard Pereire (Rue du Débarcadère), Parigi, Île-de-France
Bisteccheria · Ternes · 131 consigli e recensioni
Michael Easterbrook: This place is great, you have to queue up to go in, and they serve everyone one the same thing (steak and chips). I recommend getting there 15 mins before opening time, to get in on first sitting.
João Paulo Durão: One of the most beautiful places in Paris. On the middle two magnificent fountauns. If u look to ur right u get the Champs Elysées and the Arc du Tryoumphe at the the end.
Place Georges Pompidou (Rue Beaubourg), Parigi, Île-de-France
Museo d'arte · Hôtel-de-Ville · 610 consigli e recensioni
Pierre Valade: view from the top of the museum is one of my favorite! there is also a nice restaurant there. if you enjoy modern art and architecture (you do, right?), then you'll love this place.
