Logistics & Planning
Parking: Union Square garage nearby ($25-35/night), street parking nearly impossible, most walk from hotels

Vegan options: No - no vegan cheese or specialty options

Good to Know
Is this good for a first date? Definitely not - fluorescent lighting, basic counter service, and drunk late-night crowds make this purely functional, not romantic
Can I get a table without a reservation? No reservations needed or taken - limited seating is first-come first-served, most people take out especially late night
Is it kid-friendly? Daytime yes for quick meals, but avoid after 10pm when bar crowds arrive - basic menu works for picky eaters
Best For
Better for: Only pizza option after midnight near Union Square hotels, cheapest full pizzas in area, and reliable when everything else is closed
Skip if: You have literally any other option open - every other pizza spot in 94102 has better quality, this is purely about convenience and hours
