Okay, I came to this place with 4 of my friends for a nice night out, and we had great fun here.
Well first of all, the outside signage of this restaurant looks pretty aged and uninteresting, BUT once you get inside...the interior is amazing, all traditional looking and such with varnished wood etc. The sushi chefs greeted us with a loud Hello. On the sushi bar, they have a TV set , and I noticed they have some kind of evangelion/anime vinyl figures on the shelves behind where they work! Don't I have good eyes? Hahaha!
Well, on to the food. I ordered the Teriyaki Chicken bento thingy, the others got california rolls, tuna rolls and an assorted sashimi. The servings were pretty solid, in fact when my order came I knew my stomach wasn't big enough to hold all that food! So we just shared. The sushi rolls were nice, except the wasabi seemed to be more potent than other places. Everything was pretty good, but the Korokke that came with the box was especially nice. Value is awesome considering the food portion you receive.
Service was quite alright There were around 2 to 3 waiting tables and were really attentive at the start, even checking tables if they're OK, but seemed to move focus on to the newer customers later on. My friend actually asked the sushi chef to give him the bill, since the waiter/waitress were nowhere to be found.
Lastly, the ambience. Tenkai is a bit more different than other midscale Sushi restaurants because while other restaurants are more geared toward more seats = more customers idea, this place seemed more intimate and more private..It was so nice to not have to hear other loud customers in an asian foods restaurant. Oh, and the classic jazz music they had on were great, very relaxing!
Overall, it was a great dining experience. Actually felt very cozy despite being a sushi restaurant...will definitely visit again!
