Hello all. We are throwing a bday dinner for a girlfriend. We will be 7 women - pretty sophisticated, trendy, hip. Food should be good/ineresting but doesn't have to rock our world. We want a hot, fabulous, place where we can linger, drink (heavily) and maybe even hang out afterwards. I chose Mantra based on a recommendation and quick perusal of its website. That OmBar looks hot. Any thoughts on the place? And where might we head to afterwards to continue the revelry? Isn't it near some good spots? And what is the "ladder district" I am hearing about? I am in Boston a lot and lived there 6 years and have never heard of it. Money not an issue.
