We went to the Atlas Room this last weekend, and came away very impressed. We don't get out to H Street to often, and this place had been on my list for a while (along with Granville Moore's). The dining room is small, which is a nice change; you can actually have a pleasant conversation without having to raise your voice. We were interested in most of the menu items (they draw inspiration from around the globe using local ingredients), but settled on the kimchi gazpacho, field greens, short rib ravioli, pulled beef sopes, pork loin and lamb duo. The kimchi gazpacho was pretty good, but the "shrimp-iness" lingered a little in the aftertaste. Also, the chicken wontons were a bit bland. The field greens was a pretty typical salad. The short rib ravioli was great though. I could eat a whole bowl of them (3 came to an order). The pork loin was also very good. It came with a delicious yam-pineapple mash and a chili-caramel sauce, and the only complaint (which was overlooked because the mash/sauce covered it up) was the pork was a bit dry. The pulled beef sopes came upside down, with the black bean sope on top of the pulled beef in mole with a jicama slaw. These were also quite good, but the denseness of the black bean sope took it down a notch for me, but still quite good. Lastly, the lamb duo (though couldn't tell the difference between the two) was also very good. The lamb (med rare) was juicy and tender. The root vegetable gratin almost stole the show for this dish though. I normally am not a big fan of "au gratin", but this was very good - sliced thin and not very creamy.
I am surprised I haven't seen anything on this place on CH. This was one of our better meals in DC. Service was good; attentive and knowledgeable without constantly being all up in our business.
