If you've got your heart set on Fire & Ice, count me in!

If those plans fall through, I can second Dale's recommendation of Bartley's Burgers, though it's not by any means a "Big Dinner Out with Friends" kind of place. There's a pub near Harvard called Tommy Doyle's that I frequent, and I've certainly had a hankering for more Brazilian BBQ ever since the local furs introduced me to it.

(Oh my goodness, I'm starting to sound like someone who actually knows the neighborhood!)
