I live just west of Boston. Unfortunately I will be working on Thurs. I'm not familiar with Victoria's Diner, however, Roxbury can be a rough part of town. Boston is not a large city in terms of miles. Here are two places I recommend: One is Doyles's Cafe in the Jamaica Plain part of the city, at # 3484 Washington St, Boston, MA 02130-2602. Doyles is an old Irish pub. It has lots of old Boston connections. Nearly every politician for the last 75 years has visited there and has their picture on the wall. If you have seen the movie "Mystic River", then you have seen the Doyle's bar, it is where the girl danced on the bar before being killed. Doyles is also a couple of blocks from the Sam Adams brewery.
The other place is Jacob Wirth's. It is closer to down-town, a couple of blocks from the Boston Common. http://www.jacobwirth.com/
Hope this helps.
