Try The Sevens, 77 Charles St. This is a dive bar with decent pub grub, within stumbling distance of your hotel. The 21st Amendment , 150 Bowdoin, is also within walking distance but can get really packed on friday nights.
I watched the KSU game at the sports grille on Saturday. Nice place and some awesome sports memorabalia. We sat down next to a tribute to the immortal Bobby Orr. I knew it was a good sign since that was a boyhood hero of mine. Its a 10 minute walk from Quincy market
