First things first...
1. I'm not a huge fan of hibachi style dining.
2. I'm somewhat new to sushi.
3. It is located in a strip mall - near Menards - close to Rt 59.
Our first trips to Kiku were for the hibachi. We never really strayed from the Hibachi Filet for Two - minus one trip where I opted for the Filet/Lobster combo. The wife and I compromise on how the steak is cooked - I prefer medium rare - she prefers medium - so we get medium

The meat is always tender - and cooked as requested.
Originally, we'd start with the asparagus beef roll for an appetizer. Then we added a California roll just for fun.
We have our favorite cook (Hong) - who always greets us with a smile - even if we're sitting at the sushi bar (more on that later).
My wife wasn't a big seafood eater but is becoming a convert. Her idea of seafood was Long John Silvers. After a trip to the ER for gallstones - we're cutting out fats, eating more natural and adding fish to our diets. Enter sushi...
Personally, I think this is where Kiku shines. We've now been there for sushi four times. It started fairly simple - California rolls, Kappa Maki, Philly Roll (salmon with cream cheese - delightful) - I'd order something slightly more adventurous (remember I'm new) - Lobster Dynamite (Lobster, Scallop, Crab & Cucumber - with some warm topping), Ecuador (Tuna, Hamachi, Jalepeno, Cilantro, Tobiko) and most recently the Seared Tuna with Spicy Tuna.
After reading some different articles on sushi etiquette - I now leave the soy & wasabi alone. Occasionally taking some ginger to cleanse the palate. Our meals have gone from each of us ordering our own - and splitting another to each of us ordering 2. What started as a $40 dinner (including cocktails) - is back up to $60, $70...
We'll go later so we can chat with Yamada - one of the sushi chef. He's been a sushi chef for 25 years. We're given Japanese lessons by the owner (Steve) - and it always brings a smile to the chefs' faces (I think they're laughing at us).
The service from the wait staff has never been outstanding - average at best. I've always felt welcomed by management and the chefs (hibachi and sushi). Still a fun place for dinner. I'd recommend reservations for hibachi - we've never had to wait if sitting at the sushi bar.
