Wow. I would give this place a 2 except I'm feeling generous because I know they just opened. The food was good, in particular the chicken, Takoyaki, and the Korean tacos. The udon noodle soup was mediocre and the popcorn chicken was poor - had very little chicken to it.
So why am I giving it a 3? We had reservations but we had to remind them to seat us even though our table was clearly open and ready.
Once seated, we sat for 20 min with no waiter and no water. We would have left but it's not fun to pack up 2 little kids and haul them around. Eventually I complained, and 5 min later someone (not our waiter) felt sorry for us and took our drink order.
Eventually we placed our order and even longer still our food came out---except the chicken. The waiter asked us if we still wanted in---that's how long it took. Of course we still wanted it! That's what Bob Chon is famous for! -_-
Thankfully the did the chicken right. If the manager had come over to apologize- I would have given them a pass- but he didn't deem it necessary to walk around to talk to anyone but the front staff.
The free valet was nice, and the guys doing it were patient as we had to buckle in a baby and great about telling us to wait inside so we wouldn't be cold.
I know Bon Chon will hit its stride eventually but for now, if you are in a hurry or have kids who can't sit around for long- I'd skip it.
