Can't say a bad thing about Room 112. Reviews on Yelp were mixed... A lot of comments about the size of the restaurant. I chose 112 over Fujo and Enso based on Yelp, and I'm glad that I did.
I came around 8PM on a Tuesday night, and while all of the seats at the sushi bar were occupied (all 6 of them...), there were only 2 other parties seated at tables. In my opinion, and having been to some small sushi bars, this place is just the right size. About 15 tables, mostly 4-tops, which means that the chefs can handle their guests and you can still feel like you're not just dining at home.
The maki rolls I ordered were good (nothing incredible, but the fish was fresh) and the service was excellent. Prices were respectable as well (keeping in mind that I'm used to prices in the DC market...).
Would absolutely recommend, and will return to again.
