Just stay off Pigalle’s night clubs, they rip you off. I don’t know about disco clubs, but if you’re into movies there’s plenty of theatres…in the Latin Quarter many are of the “cinema d’ essai” kind with old movies and classics.

What part of town are you staying in ? And what sort of things would you like to do in the evenings – pubs, clubs…?

(And I would try to avoid Pigalle even during the daytime).

and, of course, we can meet for a drink ;-°

if you are there on a friday evening, the Louvre is open ‘til midnight I think.. that’s great visiting that museum at night :-)

in centre pompidou is a lot of life at night aswel, but be careful coz it’s dangerous for tourists too.

The Lapin Agile is a really fun little cabaret house very near the Sacre Coeur. Every evening except, Mondays I think? they sing and serve drinks from about 9pm until 2am. You get a free “house drink” with admission that is pretty nuts.

It’s a LOT of fun. Dark, music, alcohol, very very French.

I’ve never felt unsafe at night in Paris any of the many times I’ve traveled there alone. You simply need to apply the rules of being alone in any major city to Paris. That is, you travel only populated streets at night. If that’s not possible, you take cabs to your destinations.

The only place that I say you must absolutely avoid at night is the river bank.

What to do at night? I love live music, so I recommend seeing shows.

I agree with bboysgirl….
Simply walking around Paris is entertainment for me.

As for dining alone, lots of people do it due to business travel – I’ve seen singles reading books while dining in some of the world’s finest restaurants. I find that I’m well cared for when I dine alone – in Paris or anywhere.

I’ve never felt unsafe in MOST areas but like all large cities there are places not so safe and it’s easy to wander into them. Do you have an iphone? Rough Planet (I think) now has a Paris Ap with so much info on it you don’t need any other guide. I have gone there several times by myself. I like to visit the department stores Printemps and Galleries Lafayette in the evening as the tourists are gone and they are open until 10 pm usually. You can spend hours in those places even if you’re not buying anything. As to dining, make sure and get off the beaten path, tourist areas. Then just get a small table on the street and people watch, read, enjoy your meal. Parisian cafes (so long as your not in the tourist spots) are very amenable to single diners (particularly ladies of any age!) and unlike the US, you won’t ever feel rushed to give up your table. Take a book, get a carafe of wine, and enjoy your evening. Paris has many, many parks and green spaces where families, individuals, couples, everyone goes in the evening time. It’s also a great place to lay down on the grass or sit on a bench. Read up on the beautiful parks. As to nightlife, I would look on facebook and just as in the US there are clubs and promoters and you can get on their lists so as to be on the guest list. Oh and true about the river bank. Not safe anywhere at night. But a must do is to sit on the steps of the Trocadero and watch the tower light up. So beautiful. Again, bring a book and just relax. So many there doing the same thing. First thing when you arrive, go to a news kiosk and buy a Pariscope. It’s an English (make sure you get the one in English) paper telling all that is going on in the city that week such as concerts, exhibitions, fairs, and so on. You will find many things in there to do. Personally I enjoy traveling by myself as you don’t have to conform your schedule to anyone else and can do what suits YOU! In Paris, that’s a really good thing!

Hello !

I am with conf: avoid the streets around Pigalle at night. I hate this part of the city. If you can find movies in English or if you’re good enought at French, you can definitely enjoy one of the many cinemas around town ;)

There is a “pub” I like in Saint-Germain-des-Prés: “Le Cool In”. It’s an Irish pub. Try to go there when there’s a rugby match :) The nearest subway station is Odeon. Let me know if you need more info about it.

I live alone in Paris but often eat at my places. If you like sushi (and do not mind spending 20€ for your meal), you can go to Planet Sushi at Place de la Bastille. There is a moving tray (I love those!) and you won’t have to eat in front of an empty chair (because there are seats directly facing the tray).
Or you could eat a sandwich and walk around town (Quartier Saint-Michel).

Have fun :)
