We have had Mobile Teppanyaki twice now and it's really fun if you have a bunch of people.
They bring out the actual Teppanyaki hot plate and set up chairs, tables, utensils – everything.
They generally bring two people along (one chef to cook and entertain) and one to set up and tidy up.
Terry Chen is very entertaining and it doesn't feel at all weird to have them at your home. They throw in some funny twists to the normal teppanyaki entertainment.
The best bit is that it does not cost that much more than normal Teppanyaki, they set it all up and THEY CLEAN IT ALL UP! WOO!
It's a fun, laid back way to do Teppanyaki.

Approximate cost: $35-$75
