waterfront/south station area
a friend and I will be attending a concert at the bank of america pavillion soon, and I'm not very familiar with boston geography. We'll be taking the T in and getting off at South Station or Broadway and would like to eat around there before we walk along the waterfront to the venue. I will eat anything, but my friend prefers Thai or Vietnamese. Anything good and authentic around those parts? I know about South Station's proximity to Chinatown, but don't know whether or not there's any SE asian there. help me out! thank you.
also -- I am a vegetarian, and my friend does not eat red meat.
