Paris restaurant recommendation?

[AuntieMaggie]

We're staying not far from the Louvre in Paris - can anyone recommend a restaurant which is nice but not too pricey?

Le grand Colbert in rue Vivienne - you'll need to book if you want to get in before about 22h but it's good fun

Why good fun?

Very busy, friendly staff, generally good vibe. Haven't been for about 9 years, but it's the kind of place I doubt changes very much. here
