Famous Bao --- Shaanxi / Xi'an food (Berkeley)

Went last night. We had the Spiced Beef Burger (Rou jia mo 肉夹馍) Cumin Lamb Hand Pulled Noodles and Spicy Veggie Iron Pot.
The Rou jia mo was not to my liking the Bread was kinda damp and textureless , perhaps low quality flour? It seemed premade to me so I asked and was assured it was made in house. They explained that there are a couple of different ways of making them. I was comparing to the ones that I had had at Terracotta Warrior.
The other two dishes were very good.
The Szechuan Pepper used in the Iron Pot was the most aromatic and pungent that I have every had. Really beautiful Citrus-Pine Scent and flavor. Perhaps the Green variety. Nice mix of Veggies Lotus Root, Bamboo Pith, Pressed Tofu, Celery, Cabbage etc…
Noodles had a lovely chew to them Topping could have been a bit more pungent but still very good.
Staff was super friendly and interested in our impressions especially the young Man who seemed to be coordinating everything
There a couple of negatives about the space, though they will wane with time.
No hand held Menus yet
Varnish on the homemade Tables stinks like Solvents
Plastic Glasses also off gassing ie Water tastes horrible
We will be back, but with our own Water Container
