Well, if you've never been to Teppan this could be a fun experience. Unfortunately, it's the exact same show from each Teppan chef at every table. Tossing an egg around, making a choo choo train from the onion and tossing pieces of shrimp into people's mouths (or in their faces as im that happened to two people in our group.
Their prices are ridiculous and be prepared to spend a lot of money. They use frozen Gyoza ($7 for a bag of 50 or so) and charge $8-$9 for 5 of them. The service is slow and the waitresses talk crap about their tables (including yours) in another language.
Getting drinks takes quite some time so I would normally recommend going to the bar, but that would depend on who's bartending. The music is fun and the patio is great!!
The happy hour isn't too bad either.
