Write the comparative or superlative to complete the sentence. este fin de semana, celebraremos mi cumpleaños en mi restaurante favorito. este restaurante tiene worst-2 palabras) menú porque todo es expensive).

Just in case:
Superlative is when you exaggerate something, say: something you saw was very pretty and you wanted to emphasize that, you would say super pretty.

Comparative is simply (how the title says) the words you use to compare something.

It would be:
Este restaurante tiene el peor (comparative) menú porque todo es carísimo (superlative).

Good luck!
