If you want a slightly funky, unconventional, high-end sushi experience, why not head over to the hump in the Marunouchi area. You'll enjoy the view, atmosphere, and the food for a moderate price.
the hump is found on the second floor of the Meiji Yasuda Seimei building (otherwise known as Marunouchi My Plaza). Since most of the restaurants are in the basement, on the restaurant floors, this is a bit secluded and hidden. Inside, it has a lounge-like atmosphere, dimly lit with modern furniture. From their large windows, you can see the Imperial Palace right across the road. At first glance, you would not know this is a sushi restaurant. But sure enough, in the back, there's a counter and itamae squeezing some sushi.
the hump was originally a sushi restaurant in Santa Monica, in a private heliport, serving to only select customers. They opened a restaurant here in Marunouchi and serve to the Japanese crowd, traditional edomae sushi as well as California style rolls. The sushi is good. That you're not sitting right in front of the itamae-san and ordering from him does not lower the quality. The fish is fresh and delicious, of the standard you'd expect from the Marunouchi area. The pieces are shockingly small though (or kawaii, depending on your viewpoint), even for Japanese standards. I ordered the naminigiri from the edomae sushi section of the menu which was 8 pieces of standard nigiri for 2950yen. If you're going there to stuff yourself, well, first of all, I wouldn't recommend sushi. Second of all, this place is especially small portions -- I suggest ordering more than you would normally. I did not get a chance to try any of the rolls, so unfortunately, I cannot comment on those.
Overall, I loved the experience. It was a chance to eat sushi in a very foreign atmosphere in Japan. I would suggest maybe coming here on a date, perhaps. There's a bar that's open late, so it's good for dinner and some drinks afterwards as well.
This is another one of those places in the office buildings of the Marunouchi area. At lunch times, it's filled with suited workers catching a quick, satisfying, filling lunch. At dinner times, there are those who are working late or are finished and drinking away their stress.
If you're a part of that crowd of Marunouchi salarymen/women, this might be another choice to add to your lunch or late dinners. It's a very standard restaurant chain you'd expect from restaurant floors you see in an office building. Mind you, it is in Marunouchi so it's slightly better than some random place anywhere else.
I wouldn't come here if I weren't working near here -- there's nothing special about this place. But then again, the food isn't bad, I've never left complaining.
Saboten is a very typical, standard tonkatsu chain. Their price and quality is in line with Wako, another tonkatsu chain. And like Wako, they also serve their tonkatsu with sesame, which you grind to your liking, and free refills on their cabbage and rice.
The tonkatsu is good though, despite being very typical. You can spend a little more and order the iberico pork tonkatsu if you really want good tonkatsu. The sauce is on the slightly sweeter side, which surprisingly matches really well with the cutlet.
I like coming here for lunch. It's very convenient for those working in the Marunouchi area and is very filling. But this is not really a business dinner place. It's a very low-key, chain restaurant -- that must not be misunderstood.
Anyone going for yakiniku in the Marubiru is expecting the best of the best. In quality, quantity, and atmosphere, there can be no compromise. That having been said, I can say with absolute integrity that anyone leaving Toraji is leaving satisfied. Toraji delivers on all respects.
Atmosphere: It's classy and high-end, but remains lively and exciting (it IS yakiniku). It's very clean and well ventilated -- no stickiness or smokiness. The staff is on top of their game and even includes Koreans, so there seems a degree of authenticity (though don't get me wrong, it's very much Japanese yakiniku served here).
Food: I had myself the 6000yen course, for which I was very satisfied. The meat was pink and marbled, almost like toro. It was nice and thick as well. Kalbi was delicious, of course, but their tan was amazing as well. The course included beef sashimi, and despite not being so excited about raw beef, I had myself a welcome surprise. Not only the quality, but I have no complaints with their quantity either. By the time the bibinba came I was already stuffed. After fitting the bibinba in my stomach, I then had to find room for dessert. Both of which tasted great despite being so full.
This is a great place to come with friends/family and even for the slightly casual business occasions too. I highly recommend it.
