Your wife/kids can choose from 4 non-spicy noodle soups, 2 non-spicy dumplings.
Full menu here (courtesy of WonHo Photo):
Most of the non-spicy noodles were “home style”, ie., bowls of poverty noodle created by throwing in the kitchen sink, then adding a fried egg on top.
One of the best dishes is the pig lips, which were absolutely not spicy. To get into the “fun stuff”, a lil tolerance of spiciness is required. That said, multiple Chinese children have been to known to demolish the “clear broth zhajiang mian”.
The best mains, both of which not mentioned in print so far, are actually the 2 dumplings: the salty, spicy and sour chaoshou (wontons seen below), and zhong dumpling (nearly identical to the version found at Chengdu Taste, which means it’s balanced and glorious).
A doable meal would be: one bowl of non-spicy dry noodle to be shared between wife/child, order something confrontational for yourself, toss in the steamed eggs with pork (served in cute, branded, enamel cups), add the pork lips, and the pickled radished (really spicy). Don’t forget to ask for the soothing “noodle broth” (ala otafuku) at the end of the meal. Add a bit of the sweet/sour/spicy broth from the zhong dumplings, and be enlightened like a Chengduer.
For an authentic solo brunch, I’d take-out a bowl of the salty silken tofu (better than any agedashi) and call it a day:
Pro tip: take the smoked plum tea home, add 4 shots of tequila; floor.
