I'm planning to eat alone at Lee Jae-mo Pizza in Busan soon, please recommend some menu items...

I am a male in my late 30s with a hearty appetite.
I absolutely love dairy products like cheese, milk, and butter to the point of being obsessed.
I have an upcoming business trip to Busan
and I'm planning to visit Lee Jae-mo Pizza for the first time.
I was wondering if they accept solo diners...
Also, please recommend some menu items ㅠ.ㅠ
(My accommodation is near Gwangalli, so I'm also wondering if delivery is available...)
