Foodwise, Soundbites on B'way is really incredible. If it's warm out, a trick to avoiding the long line is to go to the counter for take out. Then eat a picnic breakfast in Powderhouse Park.

You're going to find breakfast-all-day a rarity in the Boston area. I'm from the Mid-Atlantic where all night diners are a staple, and I really missed them when I moved to New England. One good breakfast-all-day place I like is the S&S Deli in Inman Square. Definitely worth hopping over a few neighborhoods for.
