Can anyone recall about how much their dinner prix fixe menus are?

Thanks

fr.parisinfo.com sez 14-19 € (but I see no date so don't know how old the info).

mmmm.free.fr has a testimonial saying "n'hésitez pas une seconde pour ce petit restau très sympa, sans prétention, au choix très respectable pour un menu entrée-plat-dessert à 18 euros."

That's appetizer-main course-dessert for 18 €.

A la carte items 20 €.

No, don't remember the price, but do remember how much we enjoyed it - tres sympa. And good value.

Would I need a reservation for a Sunday night around 8:45 - 9?

Wow, they did raise their prices! In 2004 we had their lunch menu at 12 euro (3 courses). Two courses were only 10 euro.
We also very much enjoyed it, not only the food but also the atmosphere at noon whit all the busy office people.
I don't know how busy it gets for dinner but for lunch either by early or make a reservation.
Bon appétit!

You probably would need to reserve. In the summer, we ate around 7pm or just about when it opened and within 15 minutes, the place was full!
