I just tried my second largest city attempt and ended with 53 on large, continents, epic, monarch (Note:with advanced start 600 points). This might be general knowledge but I built the National Park national wonder in the chosen city with Globe Theater. So no unhappiness or unhealthiness from population, making food the only limit. It seems like an easy trade for the National Epic (+100 gp pts.) This makes bee-lining to future tech's +1 health(s) unnecessary.
And Cereal Mills gives more food/resource than Sid's Sushi.
