Simulated Situation/Making suggestions
In a simulated situation you can use simple statements like "This is good!". Instead of saying only simple sentences like that, you can improve your style by using the following phrases:
"How about going to the cinema?"
"Why don’t we have a meal in that new restaurant?"

"Let’s invite some friends round for dinner."

asking for opinions
"What do you think about that?"

So shall we do /buy /.... ?
I guess...would be (the) best because ...
We have decided to ...
