Hello Arek, "would like " is an expression that means to desire or want . In your sentences add "to" between like and the second verb. I would like to buy....... I would like to go ..... :)

ハンバーグを買いたい。 レストランに行きたい。

when you use WOULD LIKE TO , you express a desire , a wish . your desires and wishes are likely to happen but not now maybe sooner or later

Hi ....... Subject + Would like + to + verb ( simple form ) + complement
