if you're feeling a bit more adventurous than just sushi omakase for dinner then i'd recommend you trying a KAISEKI meal at SUGIYAMA. kaiseki is a multi-course dinner usually at least 7 courses that the chef prepares that lets you experience all the diversity of japanese cuisine. and of the few kaiseki restaurants in nyc Sugiyama is by far the best (much better than kai). their normal omakase is $80-$100-$120 and their omakase kaiseki starts at $100 and with Kobe beef it is $150. it includes sushi at the end so you won't miss out.
my $100 experience at Sugiyama included a huge block of monkfish liver that was so soft and creamy it felt like tofu in my mouth, lobster where the brain and organs were turned into a sauce, assorted salads, sashmi, steak and octopus cooked on a bed of stone, and 6 pieces of sublime sushi.
also the chef, Mr Nao Sugiyama and his wife are the most pleasant people to dine and experience a kaiseki with. they treat you as a VIP guest at their home and provide you with a warmth of service that lets you digest all that gorgeous food with glee... try it and you won't be disappointed...
sugiyama is on 55th st b/w 8th ave and bway.
