I went to the new Scholars Inn on Mass Ave over the weekend. Wow that is the coolest, classiest restaurant I have ever been too. Won't be for everyone. It is pricey - with tip it was $112.00 (for two) and we didn't have desert, or salad and each of us had only 1 drink. But if you want to impress your date - it is a great place to go. I've never seen an interior like that - hard to describe - food was excellent also. If you want to have a dinning experience that you wont soon forget, I highly recommend it.
The pictures on the website give a decent idea of what the interior looks like -
