Since discovering it, I have been here two times. Highly recommend the yin yang option when selecting your broth. Life is too short to simply pick one! Since having this dining experience on both the east and west coasts, I was ecstatic to find a place offering this cuisine in Phoenix. Location is great as there is ample parking. Depending on the night and the hour you go, the wait time can be slightly long due to their limited number of tables. The waiting staff is great, as they will help new diners out by providing suggested cooking times for each ingredient you order in case one is not familiar and want to try something new on the menu.
A few reasons why I didn't rate them a 5:
1) the waiting staff might not be as attentive as you'd like them to be
2) portion sizes are slightly pricey, though one can argue you're paying for the cuisine type and experience
3) You'd think the longest thing to prepare is the broth since it prepares cooking/heating. Ya know, since all of the food is cooked by the diners. However, both times I've come here, the broth comes out first and placed onto the heating platform. To only be evaporated 15-20% while we wait 15 minutes for the uncooked food to come out.
