Smith and Wollensky is an upscale steakhouse chain with multiple locations in Boston. They specialize in prime steaks & seafood, but also have a great wine list. This Back Bay location is my favorite because the castle is beautiful. The Castle is within walking distance or a short cab from most of the conference hotels.
The restaurant is offering 10% off for any attendee of the conference, but you must remember to bring your badge! Make sure to book a general dinner reservation in the dining room using the following website. http://www.smithandwollensky.com/our-restaurants/boston-back-bay/
Of note the 10% off does not include alcoholic beverages due to stage laws.
