3.5 Metropolitan, 8, rue de Jouy in the 4th, 09.81.20.37.38, closed weekends, has a 3-course "menu" for 22 E and interesting-sounding items; it's chef'd by a close runner up on Top Chef who was 23 when he competed in it. Not that it's important but I recall taking my then-3-year old grandchild to the address (then Chiaro di Luna) when she lived with us 12 years ago and it was terrific; then apparently it became a cyber cafe, and since spring, Metropolitan.
I went with two blogger-buddies and think their take on things was probably more positive than mine, since I was in a dreadful funk made worse by not being able to hear them or the waitress in part because of the Saturne-level din. One of us had the maki de salmon fume aux legumes croquants, which were better than OK, but two of us had the creme brulee of girolles - really a girolle mousse with a layer of carmelized sugar atop - which my side mate said was too much of one texture and I said was too much period.
The one of us having the "menu' had a blindingly white breast of chicken on a schmear of mashies, another had (the winner by me) a fricassee of mussels and girolles and cleverly carved piece of potato and I had duck two ways with a poached fig that I could not finish.
The ladies were kind enough to share their desserts with me - a chocolate moussy-thing on a praline crust with a iced ball of sweet barbe de papa and a tiramisu with Nutella and banana - the latter with that same texture issue.
Our bill, complicated, but with 1/2 a bottle of wine for me and two coffees but no bottled water it was 97 E, thus 64 E a couple.
Go? Maybe if you're not in a funk and wearing hearing aids or Bose noise-blockers, but otherwise nah.
