Oh. And 2 tips
1) If you’re looking for ASPIC do not confuse it with the nearby ASICS shop on Google maps.
2) After a really nice meal with a decent amount of wine have coffee.....DO NOT have one of the two French DIPAs the waiter shows you. And under no circumstances then have the second.
And stop off at one, or all three on my recommendations. ASPIC is a short walk from Montmartre but the other two are very much in the heart of the area.
For food I was recommended this place by Goldstone1976

It was lovely on every level and, imho, exceptional value for the standard it is.
The bar area of this place is nice http://www.la-mascotte-montmartre.com/en/ . Lovely location as well. We drank wine...
