I like Supper better. I think Lil F. is more uneven. However (not that you asked), in the same neighborhood, I prefer Lavagna & Spina even more (slightly higher prices I think, but worth it). Less formal... it's really a wine bar with a good kitchen... is Il Posto Incanto (http://www.ilpostoaccanto.com/).
