I and several thousand librarians will be descending on the Hynes Convention Center next weekend, and I'm looking for something nearby to eat. I'm staying in Copley Square, but I'm willing to travel a bit on public transportation for something really good. Safe neighbourhoods are important, and I'm on a budget, but I'm willing to spend more if it's really good (although Mistral-type prices are a wee bit out of my range). Is there anything in the area that I really shouldn't miss? Lunch, especially; I hate having to resort to the food inside convention centers.
