We ate there several times when it was Teppenyaki (at one point with TWO toddlers) and once with a toddler and a preschooler since it was remodeled to become Teppen Edo. I won't swear to it as fact, but the dining table seems a good 4-6 inches deeper since the remodel, making the grill further away. I know they didn't push the issue of making sure the little two didn't reach to the grill as much as when it was Teppenyaki, they also didn't insist on seating the toddler at the corner like they used to.
As for sitting with other people - I normally feel bad for the people who get seated with us. We're a party of 5 usaully, sometimes 6, and 2 of those kids are under 4. Since we take up most of the table ourselves we usually get sat with a couple traveling w/o children. Most of our experiances have been good, but we had one experiance where the couple at the table with us obviously expected a grown up night out. They were older, but not old (upper 40s, early 50s), VERY well dressed -suit, heels, make up, loads of perfume & hair spray, and were having wine by the bottle with their lobster etc. Thankfully the children were all behaved that evening, but the woman of the couple was constantly looking down her nose anytime one of the kids made a peep (which was most of the meal since they were talking, but not being loud). That was the exception though. The rule has been a good experiance with either active conversation from our tablemates or indifference. When faced with this we rearrange so that all the kids are between dh and I and not next to the stranger.
