Downtime in Boston?

I will be in Boston for a couple days next week, and thought it would be a good excuse to do some legwork on the Modern Gentleman’s Guide to Boston. While I plan to use the interwebs to find some of the places I’ll visit, I figured it would be even better to go directly to those that share many of my preferences: you, our loyal blog reader. 

Any thoughts on the best steak house in Boston (no chains please)? Best martini? Barbershop? Wine shop? Spot for a business lunch?
