Is the word pizzaria the same in Brazilian and European Portuguese?

Yes

The spelling, meaning, and grammatical function of "pizzaria" are identical in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, the vowels are generally more open and the "r" sound varies by region (often a flap or slightly aspirated), whereas in Continental Portuguese, the vowels are more closed or reduced, and the "r" is typically a distinct alveolar tap.
