Kass and I went to La Mirabelle tonite. This is a place we wandered into when we lived at 88th and West End. We went with a couple who has a child in Cole's class this year at Calhoun. Great conversation, great food.
If you want a real New York French brasserie, do not go here. If you want authentic French food, go here.
I'll warn you that the first thing that you'll notice is that you're the youngest person in the restaurant (provided that you're younger than 70 ... but given you're reading this site, the chances are you're younger than 70). The food is consistently great -- endive salad, onion soup, steak frittes, mussels (Fridays only) and Monk fish rock.
For those of you from DC, think La Ferme but cheaper and closer to my apartment in NYC.
