After spending Thanksgiving with our respective families, my partner and I enjoy celebrating Christmas by ourselves. This usually involves dinner on Christmas Day at one of the tonier places in town. Some of the places we've tried over the years are: ONE IF BY LAND, TIBS ( just okay), LA COTE BASQUE (magnificent), SEA GRILL ( deiicious and festive), BOX TREE ( an incredible experience the first time that we haven't been able to duplcate on return visits). This year, we're considering La Grenouille--any thoughts about that, foodie brethren, or other recommendations??? Thanks.
