I think it's better to think of some warm names, which is in line with the concept of low price and tasteless of LZ's main products and gives people a warm feeling.
Because LZ's main dish is soup, it might as well be called soup house, but in order to attract more guests and let others think that it is not limited to this dish, LZ may as well be called Baiweiju chestnut chicken old shop. Now people eat old shops and so on.
Of course, these names are for reference only. What I offered LZ was mainly an idea.
If LZ has any inspiration, you might as well write it down immediately. After all, your own shop can only come up with a more suitable name according to your own experience and feelings.
Finally, I wish LZ a prosperous business.
