Romantic restaurant in Paris for less than 100 euros (give or take)?

I'm a bit wary of making a recommendation that is not based on my own experience, but if I were to be in Paris, this is where I'd go for a recommendation: http://www.davidlebovitz.com/ is an American living in Paris. He has a food blog and has published a couple of books. Here ishttp://www.davidlebovitz.com/paris/ on places to go eat in Paris.

We had a really outstanding meal last fall at http://www.youpietvoila.com/. Sounds like it's exactly what you're looking for. (Plus it's in the 10th, so way outside of the normal tourist areas.) You might also like http://verjusparis.com/, although it's a bit above your price range (~60 euros per person).

For our wedding anniversary (for which we happened to be in Paris), we went to http://www.le-moderne.fr/.

Was there recently and kept ending up in this place: http://www.tripadvisor.com/Restaurant_Review-g187147-d2445348-Reviews-L_elephant_du_Nil-Paris_Ile_de_France.html. They dim the lights at night. The food was good and the staff are as helpful as you need them to be. It's right off the Seine so the 'late night walk' can happen. The area, Marais, is hive of streets to wander where tea shops, wine bars, and chocolaterias abound. We spent a lot of time Montmarte and if you wander off the main streets you'll keep encountering wonderful, little eateries. We did organic veggie spots, amazing Italian with home made noodles, straight up French cuisine, and every place had a decent wine selection. Most of the 'nicer' places were devoid of kids and had great atmosphere.

Seconding sciencegeek's recommendation of reading David Lebovitz; not only is he a food blogger and writer, he http://www.davidlebovitz.com/about/, if that gives you a better idea of the kind of food he appreciates to see if it matches up with what you'd like. I wish I had more personal recommendations, but it's been too long since I was there. Enjoy!

Hey, I'll be there then too. If you're interested in history of science, I'll be giving a talk March 13 at the ENS (rue d'Ulm). Probably not, though.... If you don't mind crossing the Seine to the 1st (on the border with the 2nd, a short walk from where you are), I would recommend that you check out http://www.maceorestaurant.com/, in the rue des Petits-Champs, just behind the Palais-Royal. I have never had a bad meal there. The menus are reasonably priced, they have vegetarian options (not vegan--this is Paris, after all), and the wine list is excellent (the restaurant is owned by the owners of Willy's Wine Bar, just a few doors down). You could also try the Atelier de Joël Robuchon, not too far from where you'll be staying. It's not exactly white-tablecloth romantic. Think of eating at a Woolworth's lunch counter, but with better decor and, above all, exquisite French food. They take reservations only for the first seating, which is ridiculously early for Paris (6:30 pm, if I recall correctly); after that, it's show up and wait in line. But you'll get a highly memorable dinner for half or a third of the price of a fancier place.

P.S. I would have recommended my favorite restaurant of all time in Paris, Le Pamphlet, but it closed. Other possibilities (Google for more info): - Cotte Rôti, an up-and-coming place in the 12th near the Marché d'Aligre - Fish La Boissonnerie, not too far from you (maybe more noisy than romantic, though) - Le Bouillon Racine, close to you in the 6th, lovely Art Nouveau dining room and good traditional cuisine - Le Bastide Odéon, also relatively close to you, good traditional food. I'll also put in a plug for a trip to the wilds of the 20th arrondissement, not too far from Nation: - Les Allobroges. Not only is this an excellent place to get traditional southwestern French cuisine in a quiet, elegant setting, the proprietors even served me and my guest a meal on a night when they were normally closed. They had a private party that evening in the rear dining room, so when I called to ask for a table, they said they could accommodate me in the front.

I lived in Paris for a few years and used David Lebovitz's blog a lot for recs, although he doesn't focus exclusively on restaurants so you'll have to skim. Another good Paris blogger who does focus on eating out is John Talbott (http://johntalbottsparis.typepad.com/). He includes a lot of higher-end but decently priced places and has his blog organized by arrondissement so you can find what you're looking for. I found his reviews very spot on and had a number of excellent meals thanks to his blog.
