"Vorrei" is the conditional form of the verb "volere" (to want). In Italy, it is considered rude to use "Voglio" (I want) when ordering food or drinks. Always use "Vorrei" (I would like) or simply state the item followed by "per favore" (please).

In Italian, flavors or fillings are expressed using the preposition "a" combined with the definite article (il, la, etc.). "Al" (a + il) is used for masculine nouns, and "Alla" (a + la) for feminine nouns.

Use "Un, Uno, Una, Un'" for "a/an" (indefinite). Use "Il, Lo, La, L', I, Gli, Le" for "the" (definite). Which one you choose depends on the gender of the noun and the first letter of the word.
