Yes and yes. Lunch starts at 12:00. I love Teppen Edo. My DD was 28 mths last time and will be almost 3 this time when we go. Taking a toddler is not a problem at all. With them sitting in the high chair, there is NO WAY they could reach the grill, unless they stood on the highchair and leaned WAY over. Now, I was a little nervous about her shoving her plastic cup towards the grill and it going on there, but we had no problems. She liked playing with the chop sticks and watching the show. She doesn't eat well, so I just brought her a bowl of fruit but she did like the noodles!
Personally - this is one of my favorite restaurants, it is so good. We are eating there 2 times this next trip and my mom 3!!
