Game On - Probably the best sports bar/club near fenway.
Jilians - Huge place. Good for sports bar, and they have pool and bowling, and they might have a lil club downstairs.
Boston Beer works - A brewpub. Decent food, but good if you enjoy a local brew.
Brown Sugar - Good Thai restaurant on Yawkee way/Jersey st between queensbury and park. Its about a 5 min walk from fenway.
Theres a lot of clubs on Lansdown st which is where Fenway it. Tremont st and Warrenton st in the theater district, both have a couple good clubs.
Don't expect too too much this time of year. The majority of Bostonds population is college students. And school is out. I'd suggest staying to theplaces close to Fenway.
Have fun.
