Pregnant wife and I are visting for first time in a few years over Valentine's weekend. Staying in Financial District and looking for memorable places, but not necessarily "elegant" or "special occasion" places as she is not interested in playing dress-up beyond nice jeans and heels. Have done Aqua, Zuni, Postrio, Piperade in past. Friend of mine swears by Trattoria Contadina as one of the best places he's ever eaten, but I seek local opinions. Trying to avoid places that won't be gouging patrons on V-Day with overpriced set menus. Some options we've considered include: Canteen, Perbacco, Kokkari, Bix, Papa Resto and Bar Jules. Thoughts on these or others are appreciated!
