Budget? Don't go to Paris then.
Seriously go to the north and north east of Paris. You'll find a way to get cheap food around Boulevard Barbès especially around métro Chateau Rouge. Then there is Mesnilmontant where you can go out and find food. Don't forget to go to Père Lachaise cemetery ( métro same name) and have a long meditation in front of Le Mur des Fusillés (it's free!!). Have a walk through the Rue des Rosiers ( métro St Paul- Le Marais).
Museums: Institut du Monde Arabe, Musée Picasso, Musée Rodin, Beaubourg ( centre Pompidou), le louvre is cool but busy and dear, Musée d'Art Moderne, LES CATACOMBES! if you feel a bit goth, Musée de la Résistance Nationale in Champigny ( 88 avenue Marx Dormoy, Champigny) you'll probably need to get there by RER. Musée d'Art et d'Histoire du Judaisme, La Grande Mosquée de Paris ( the great mosque of paris, nice tea room) and of course you can wonder around Boulevard St Germain et around La Sorbonne ( take métro st michel et walk up). The Eiffel tower is shite.
If you are into bobo ( bourgeois boheme) things use a vélib' and go to the organic market place clichy.
Or simply ask Jeff Costello to show you around.

), cos he didn't speak English, and he wrote off my (massive) bar bill. 





So I'm going to paris this weekend and I've never been. Was wondering if anybody had any suggestions of things I shouldn't miss or just tips in general, bearing in mind I'm going on a budget. Thanks.
