What you said is too general. Yanggu is also quite big. Hehe, besides, you didn't say how much it would cost or anything.

Let me give you some restaurants for your reference, such as Changhai Food Bus Station in the square, Fried Fat Golden Triangle in Sunshine jiaozi City, Lion Building, etc. More than 20 people can also go to the buffet, which is economical. After eating, they can go to the concert and have a good time without spending too much money.
