Mushroom ears in Northeast China should be very famous! Just take your rich stuff as the main ingredient! Speaking of northeast dishes, the most famous ones I know are pork stewed vermicelli and northeast stew! I'm from Dalian, and I'm from the northeast with you! I've never been to your place. Our restaurants usually cook our seafood dishes here. Our seafood is fresh near the sea, which can also be said to be our local specialty dishes! You might as well take out your special things! Foreigners go to your place to eat your special food, of course!
Of course, they won't come to your place for an expensive dish (most people). It's economical and affordable. That's the first place! It's up to the landlord to consider it himself! There is nothing to mention about the menu. I don't know much about it there. I can't mention the menu at random!
I hope to help the landlord!
