I first went to Tenzan the same night I moved to NYC. I thought the sushi was delicious, even though I had expected worse for the price (Just being honest). First, let's start with the customer service. Even at its most hectic time, I don't ever have to wait very long for a table. The waitresses, esp. Sonya and Shelly, are divine. We are on a first name basis now, because they were so friendly and polite I couldn't help but get to know them. Even if it is your first time, they will be very accommodating to you. Second, presentation. Have you ever been to a restaurant that had good food but the place looked dirty and you just wondered who exactly made your food? Well, Tenzan is exceptionally clean. I never have to worry about hygiene, and I know that the tables and booths have been wiped and cleaned. The decor is very nice, and they always have such pretty flowers. Best thing is, its a casual restaurant (I go there in my sweats when I am desperate), but you wouldn't feel out of place if you happened to be wearing a really nice outfit. Bathrooms! So clean you can sit on them (I don't, but you could). Smell so nice and again, nice decor. Perks: Warm handtowel before you eat, this is seriously something I have become used to. If I go to a restaurant and there isnt a warm towel, I automatically frown for a second. Sushi: YUMMY! Presentation, wonderful. The rolls are really tight and hearty. The nigiri pieces are humongous. They always had a little flair to your plate (Designs, etc). Once, they messed up my order and the chefs wrote ""Sorry [my name]"" in spicy sauce. Cute! Anyways, I highly highly recommend the Spicy Girl Roll and the Special Dragon.
Pros: Customer Service, Cleanliness, Food, Presentation
Cons: Number of Tables (though not really a problem)
