French Restaurants

I went to the website for several of those restaurants and my Chrome browser provided the translation.

What browser do you use? If you use Chrome all of these restaurants should have English language websites with all the information you seek. Le Relais Entrecôte does not take reservations and serves only steak frites and salad and 3 or 4 desserts. I will refrain from giving my opinion on the hotel’s suggestions.

If you put the name of the restaurant into Google and select it, on the right side choose the website, the site will be translated in English. I did four of your list and all had English menus. You also might have to select a language tab on the site.

I don't know about the others, but I do know that Le Train Bleu is quite pricey. You might be interested in some of the videos about eating in Paris done by the Youtubers Les Frenchies. I have placed a link to one of them below. Also, many of the restaurants have a link on their website for an English translation of the menu. It may be represented by a British flag.
I speak passable French, but I still take a very small pocket dictionary that contains food terms because they are sometimes quite specific or unfamiliar to me. I have also found most servers to be very helpful, at least to the extent that their own knowledge of English allows. Don't worry, you won't starve! 😁

All of these restaurants’ websites offer an English option.

We had lunch last month at Georgette. No reservation before hand but it was close to our hotel and looked nice. We enjoyed our meal. There were seasonal items ie asparagus. I think it was about 100€; no alcohol but did have dessert.

I doubt you need a reservation at Le Relais de L'Etrecote. (actually, I looked, no reservation is possible) There are several locations, and really the only dish to get there is the Steak Frites, a set menu with steak, fries, and salad. I enjoyed it, wouldn't consider it "fine dining" more bistro type place specializing in steak frites, they also offer dessert. The price is fair, do not recall the actual price, maybe 30 euro, bit more with dessert and wine.

I believe it was Le Relais de L’Entrecote that was shown on a recent FB travel group thread of having a very long lineup (200+ people at 6:45 pm) to get in given as mentioned above no reservation is possible.

Here are a couple of places with lovely tasting menus we have enjoyed -- both have much better food than Le Train Bleu (which is a gorgeous place however). L'Initial. and Eclipses.

Take a look at https://www.thefork.com/ It will make reservations for you if you lack french and often ask for feedback.
I know le Train Bleu will serve you in English as so they should considering the prices. The rest all sound expensive so I am surprised you cannot find a link in English.

These restaurants look like you might be staying on the south side of the 6th, where there are two Relais de l´Entrecôte nearby, one on rue St Benoît and the other on blvd Montparnasse. Neither take reservations, and I have rarely seen lines very long at either, particularly if you go early.

Georgette is OK, but the nearby Le Bon Saint Pourçain is fabulous. Reservations for Georgette, la Coupole, can be made usually from 1 to 3 days in advance on their websites (in English). Allow 3 weeks for Le Bon Saint Pourçain, but it is best to call.

Le Train Bleu and le Ciel de Paris are mostly about fabulous atmosphere, but if my time were limited, I would reserve at les Ombres

Epoca should not be difficult, reservations a few days in advance should be OK; however, my choice for Italian on the Left Bank is Armani/Ristorante, just above where suits are sold (and NOT the downstairs Armani Caffé). You can make reservations on their website. Armani is really fabulous, I think it now has a star, but do not be intimidated by that.

Another Italian restaurant that is popular with local chefs, so I understand, is Restaurant Le Cherche Midi (obviously on Cherche Midi). I have not yet been, offering it only as an interesting option.

As far as l´Avenue (and I assume you are referring to the one on the Champs Elysées), it is only a place to be seen, not somewhere to be impressed by the culinary prowess of the kitchen. Some definitely would be drawn to it.

Many restaurants in Paris have switched reservations away from The Fork and moved to Zenchef. Most of the restaurants on your list do not need to be reserved 4 months in advance. If you are in Paris early October, reserve 1 to 2 months in advance, late October is even less critical, perhaps 1 month.

Also consider the many wonderful dining options in the 5th, just to the east, where prices have not risen as fast as in the 6th, and many well established restaurants with interesting chefs are still operating.

Thank you so much for all the suggestions and information, this is so helpful!

I went there on a special occasion earlier this month (2nd visit, previous one was several years ago): the food was exquisite (as you'd expect at a 1-Michelin star restaurant) but the price is steep, about €500 for 4 without drinks.

We are also traveling to the Loire Valley, Chenonceaux.
Any recommendations for restaurants there?
Thank you.
