I ate there with my wife and another couple 2 weeks ago, and we had a really great meal overall. I have not really eaten at a true izakaya previously, but I certainly would go to more if they are all like this restaurant.
We had a table in the front, which was right by the door, but perhaps better than the very noisy back room, at least if you plan on holding a conversation. Currently it is BYOB, so we brought a bottle of decent sake and some beer, and the hostess was more than helpful in getting glasses and keeping the beers cold in the back.
We ordered a ton of food, but somewhat broken up, so things came at a nice pace. Some of the things I remember are: hamachi with jalapeno (with a ponzu sauce - refreshing but nothing spectacular), Tuna Tuna (cubed tuna and avocado, which was very fresh tasting), mixed tempura (shrimp, lotus root, Japanese pumpkin, all of which had a light batter which was not greasy), kakuri katsu (panko-breaded pork belly, which was nice but I should have tried the braised pork belly dish), yakitori of beef short-rib and chicken heart (the chicken heart was one of my favorite dishes, just bursting with a deep meatiness), grilled hamachi collar (another of my favorites, with perfectly moist and flavorful fish hidden between bones and lightly dusted with salt), oyako don (chopped chicken with egg and a sweet dashi sauce over rice; it was a really, really nicely composed comfort food dish), and the "red dragon" roll (spicy shrimp, sliced tuna, unagi sauce - definitely not their strongpoint).
All of that food, and the total came to $120 without tip! $30 a person for all of that food, and some really good food no less. I think there may have even been a mistake in the bill, but I never had the chance to actually look at it closely, so I will just accept that it was a great meal for a really good price.
I would certainly go back again, so if anyone is looking for a good Japanese pub food place, this is the one to go to around here, at least for now (I think there are some others opening up very soon as well).
