A common complaint about Japanese izakayas is that food portions are tiny. If you're too slow to pick up your chopsticks, the rest of your party will polish the tiny portion of whatever it is the waiter brought. This will definitely not be the case at Uogashi; the portions are just huge. These are portions for a hungry party of rugby players.
As you walk in there's a counter with that day's fish offerings. Walk upstairs and the waitress will hand you a menu without prices. It's a bit intimidating to order out of a menu without prices, but on the whole Uogashi is not particularly expensive. The menu is divided between sashimi, shellfish, boiled items, salads and fried items. The portions are not fixed but adjusted to the number of people in your group. We ordered two kinds of fish (seabream and yellowtail), a crab salad, a platter of various boiled fish in soy sauce and sugar and a platter of fried items. The portions were just unbelievably big. I suspect we received a whole yellow tail and the crab salad was literally a small mountain of shredded lettuce with mounds of crab on top.
I have to say that the portions were just a bit too big. After a while I wished I was eating a different fish, and the fried stuff was a tad too soggy.
Uogashi is a great restaurant to gorge on seafood at reasonable prices. The place has the feel of a working-class izakaya, and would be a good spot to bring visitors to Japan to enjoy this country's amazing seafood.
