If you like eating, then you should really try
Favela Chic. It's a very good brazilian resturant near Place de la Republique. I don't know the address but tourist info will for sure. It's one of Paris's best kept secrets, and you'll have to go early (sixish) or you won't get in cause it's always packed. Tappa's, Caipirinha and great music. What I like is that you can dress casual and sit on a long table with complete stranger and it's festive, let me tell you!
Bastille is a great place to go pub hopping and clubbing at night.
The jewish area of the city called
le Marais has very trendy shops and falafel places. Good food and great for a sunday stroll.
The
Picasso museum is in one of the side streets.
There's also a small
Dali museum that has rare Alice in wonderland scetches he did, and important sculpture's.
I have an uncle living there and I go often. It's a great city to visit.
Enjoy!
