Ichiza is a solid Izakaya with fair prices, good food, and open late. Many of their items aren't on the menu, so make sure to look around on the walls for the other items. It's a small place, so it'll take awhile if you come with a large group.
Food:
1) Beef tongue - If you like the texture of tongues, then you'll like it. It was flavorful, but some of my other friends didn't like it because of its texture.

2) Beef Bowl tastes just like Yoshinoya, but with much better beef quality and without the post-meal coma.

3) Yellowtail Tartare was layered like a sandwich with chips instead of bread and topped with avocado and yellowtail poke. The fish was fresh and the sauce was delicious.

4) Miso Black Cod was buttery and soft. It was cooked to perfection! There was just enough miso for the right amount of flavor, so it wasn't overpowering.

5) Fried Calamari - It wasn't that great. I've had much better. I recommend you order something else instead because there are many better items for the same price.

Service:
The place always seems busy, so it's difficult to get everything in the time you want. Nevertheless, the staff here work hard, and they'll make sure to take care of you as long as you get the chance to flag them down.
