Hi, and welcome to OpenStreetMap! Since you requested a review, I looked over your changes here. Everything looks great generally! Here are a couple of tips:
- Since this pizza place is one business of many which share the same building structure, instead of creating an overlapping smaller building square, it's best to make it just a point ("node") within the existing larger building outline.
- In general, it's best to avoid abbreviations in OSM tags. That's because it's easy for computer to shorten words when necessary (Avenue -> Ave) but can be tricky to expand them sometimes.

Anyway, other than that your addition here looks excellent. I went ahead and fixed those issues. Let me know if you have any questions, and thanks for your contributions!!
