I agree with Kmango. Both are good but Teppan Edo is just as good as any Japanese steakhouse I've been to at home. Chefs is a must do for us every trip. Excellent food, atmosphere, and service.
And if you're worried that they just give you a few bites of food with sauce drizzled around the plate at Chefs, this is so not true. That's what I was thinking before we went and, believe me, you will not leave hungry!
