From Paris to Geneva in a week - where to stop?

I'd overnight in Lyon or spend a couple of days there too. I'd personally avoid Bocuse unless you like paying for the name - he is 86 and representative of quite a traditional style of haute cuisine. There's a good Chowhound discussion http://chowhound.chow.com/topics/801783 and http://chowhound.chow.com/topics/786697 and http://chowhound.chow.com/topics/729292 If you want to make your money go further, dine well at lunch not dinner. By all means eat in a bouchon, because it's what Lyon is famous for, but you may find the offal-heavy traditional fare is not to your liking if you don't pick somewhere with a modern twist. Quenelles and andouillette are an acquired taste. Lyon's metro system is cheap and easy to navigate, so don't worry about staying a little further out and having to go somewhere else to eat. It's generally not too hard to do. I wouldn't plan to go on a Sunday as a lot of places are shut and the centre of Lyon can be a bit of a dead zone although Vieux Lyon is more lively on Sundays. If you like food, make sure you go to http://www.thefoodmentalist.com/2011/04/les-halles-de-lyon-france.html. If you want a fun place to drink, then I'd head to the Croix Rousse - the old textile worker's district. If you want a fun night out with simpler fare somewhere atmospheric, you can't beat http://www.lyonresto.com/restaurant-Lyon/restaurant-les-Demoiselles-de-Rochefort-Lyon/restaurant-les-Demoiselles-de-Rochefort-Lyon-6017.html - a Lyon institution. It's exceedingly kitsch but fun. If you are on a budget or more hipterish, then use the http://www.petitpaume.com as your guide. It's distributed to students and is produced in Lyon for Lyonnais.

Here's a http://goo.gl/maps/N0JIN of the route. You could do very well spending a few days in Burgundy. Beaune is the big town in the middle of all the wine; Chablis is also a lovely small town to visit. Note that wine tasting in France is not quite the big business it is in the US, but there's certainly plenty to do. The Hospice de Beaune is worth a tourist visit as a break from drinking. And great restaurants all in the area. If you have a car there a large variety of lovely hotel / restaurants in the countryside; by train you'll need to stick to the bigger towns. I forget how the TGV runs, but if Lyon is on your way it's a fascinating city worth several days visit all on its own. It's got a big university too, so not so stuffy.

Just a thought - we took a side trip from Paris to go to Amsterdam for a couple days. It would be perfect for a 3 day side trip, returning to Paris. The train takes about 3.5 hours each way.

http://en.wikipedia.org/wiki/Aix-les-Bains is quite beautiful. And Lyon is awesome.

A roughly anti-clockwise approach via Beaune, Lyon and Aix-les-Bains makes a lot of sense, as you get a good set of regional transitions over relatively short distances, all decently served by TGV or regional SNCF. Going further east to Jura (Besançon, Arbois) is another option, then hugging the Swiss border southwards, but that's much more of a driving trip and probably better pencilled in for another time.

The obvious answer is Lyon. Fabulous city, and you won't find better food or wine anywhere in France. The Bocuse brasseries (nord, est, and sud, I think they ate called) will let you eat food from a multistarred chef at reasonable prices. Lyon also has a gorgeous renaissance central city and the old silk worker district is also nice. Dijon would also be directly on the way, but I might skip that in favor of a day or two in Burgundy, a couple days in Lyon, and then Annecy.

Mmmmmmmmm.... Lyon. So good. A bite sized Paris, but even better tasting.

Lyon is definitely fantastic. If for some reason you wanted another option, you have time to go the long way and head over to Alcase and work your way down via Strassbourg, Colmar, Mulhouse, and Besancon. The TGV will get you to Strassbourg from the Gare de l'Est and there are tons of regional trains in the area. Also great food and great wine, although you might have to work a bit harder to find it than in Lyon. On the plus side, maybe a better region for white wine (not that white Burgundy isn't great too). In either case, I always recommend the site http://www.lefooding.com for solid food recs in the slightly young bobo French direction, although I could well believe that Lyon has better internal guides.

I'd never heard of Bourg-en-Bresse before my husband and I spent an afternoon there between trains, but we found that city incredibly charming and accessible and low-key. Downtown is picturesque and well-maintained, with lovely cafes and ancient cobblestone streets and cute schoolkids and a nice church and limited tourists and really nice people who were accepting of my mediocre French, and we even stumbled across a hot pizza vending machine (although I suppose you might find that anywhere). As our train time neared, we realized we had wandered too far from the station, so a marvelous French woman rushed us back there in her truly ancient Fiat. So yeah, shoutout to Bourg-en-Bresse. There's not a lot of tourist appeal compared with other French cities, but it was a really nice place to be in. Another fun thing: get a map and a local bus schedule (and be prepared to walk) and go visit villages around a city. We did this in the Belfort environs, but I imagine the experience might be similar around a lot of small cities. There's plenty of nice food and wine to be had in small towns, and the people you meet will tend to be very welcoming.
