"I have mixed feelings about Yamachen's, because the service was impeccable, as was the set up for takeout. We ordered a beautiful array of sushi to take to the beach for a sunset picnic and had high expectations to the stellar reviews on Yelp. We ordered a few specialty rolls, some nigiri sushi, and a spicy yellowtail roll. In addition, we ordered gyoza.The way they packaged all of the items was fabulous. I've never had such care given to the setup for a takeout order. High quality trays with pockets for soy sauce, super high end chopsticks and napkins, each tray labeled with the items within. For that and the service via phone, I applaud this place and would give it another try.Food-wise, none of the sushi WOWed us. My favorite was my spicy yellowtail roll, which had nice chunks of fresh yellowtail and perfectly ripe avocado. I also liked the salmon nigiri. The dream roll was delicious, but I got quite a few bites of crab shell, which was a turnoff so I didn't finish that roll and it felt like a waste of money. In addition, the rolls and nigiri with tuna tasted off. I thought it was just me, but my friend also mentioned something so we both skipped the rest of those pieces.The gyoza was delicious, specifically the sauce served with it and the complimentary spring rolls may have been the best spring rolls i've ever had."
