Came by for their AYCE as I've only been trying their A La Carte menu.
Made a reservation at 630 - 640 PM and there wasnt many people which was fine with us. It was a pen/paper ordering so you write down the number you want and the quantity. The menu also lists how much they give for each section. Eg: Sushi is by 6 pieces. So you would put 1 order under quantity for 6 pieces or 2 order for 12 pieces.
Some of the servers need training as I find their attitude bad. When I asked for ginger while she was clearing the dishes, she didn't acknowledge me/my request which led me to be "wtf", but later on, she came back and brought the ginger. Another server acted the same way when I asked for another drink. The only person who really seemed to help us was (I believe) is the Manager. He was talking to some of the regular customers but he seemed the nicest and most helpful one out of all the servers that have attended to us.
Food was okay and decent. I like how it came fast... at one point our table was super packed with food and I didn't have to re-order stuff. Definitely recommend the creme brulee! Usually restaurants run out of those but not this time at Yamamoto's.
Note: The menu that they broadcast outside is different than the one they serve in the restaurant. We were fooled to think some stuff were offered like the Durian Mousse but they have changed the menu. Also, if you took a picture of the menu outside, please DO NOT use THOSE numbers while ordering as it is totally different from the ones in the menu.
