Next month I'll be staying in Boston at the Omni Parker House for a conference. I'm originally from NYC but I've been living in northern New England for way too long and I'm very anxious to get out into the city and EAT! I'd like some restaurant/bar recommendations that are in walking distance of the hotel. I don't need upscale and fancy--I'm an adventurous eater and a former food writer who loves a great atmosphere, creative menu, and just about any kind of cuisine--just nothing stodgy, fancy or touristy. Many, many thanks.
