Likely mozzarella or another non-aged cheese with higher fat and hydration for melty goodness. I haven’t been there in years, so, I’m not going to guess what ingredient they’re using.

Goat cheese and feta are fine on pizza, but it’s prepared differently. They’re nice with olive oil and no or low sauce, cured meats, dates, and something to offset and counter the saltiness.

But go on some more.
