HopMonk Tavern

Thin-crust New Haven-style pizza half a block off the Plaza, with patio seating.

The playground inside the historic plaza: two age-split structures, a sand pit, a duck pond and huge shade trees, with cheese shops, bakeries and ice cream all around.

Sonoma Plaza's garden cafe: breakfast and lunch on a leafy back patio with the duck pond playground across the square.

The original Mary's, born on Sonoma Plaza in 1959, where kids make their own pizzas (dough, sauce, cheese, toppings delivered to the table).

A playground with bocce and volleyball courts, picnic tables and the small Depot Park Museum next door.

A quarter-scale steam train that takes twenty minutes to loop through tunnels and over bridges, plus a small petting zoo and a few fairground rides. Built for under-eights.
