We'll be celebrating my husband's and his friend's birthdays at DB Bistro Moderne on a Saturday night next month. The wives would like to take the guys for a pre-dinner drink someplace pleasant nearby. The restaurant is at 55 West 44th Street. We're all in our mid-50s, which I mention so you know we're not looking for a "scene," we just want to have a nice drink in a lovely, reasonably low-key spot - perhaps with a live jazz combo or something. Any ideas?
