HELP!! - Paris ' Bistro Crawl '.....Choices are scary! Please help to eliminate!!

THANK YOU ALL for your kind and valuable feedback!
The itinerary for my up-coming Paris food-crawl is almost complete! Man! This research project is tougher than my University thesis on Aerodynamics! Ha! :rofl:

One last question if I may?!
My travelling companion is a lover of ’ Foie Gras '…especially ‘seared’! As such, for one of our bistro outing, he is planning to arm himself with ’ Cholesterol reducing Crestor ’ and feast on a ’ Foie Gras Centric ’ meal.
Is ’ Le Comptoir de la Gastronomie ’ over-hyped and touristy due to its convenient Las Halles location? Is the food good and more than acceptable as per numerous reviews I came across?..OR…Shall we head further north to more out-of-the-way Pigalle and eat at ’ Le Petit Canard '?! Looks like the duck dishes are more rustically prepared here, though the seared Foie is only available for dinner!
Guess, on top, we’ll be ordering some typical bistro food like Escargots and Onion Soup as well?! Are the two places comparable or one version ( Onion Soup ) more flavorful and complex than the other?

Thanks again! :smiley:
