A chef approached the table, rolling a tablecloth-covered cart. On it was a large mixing bowl, a whisk, a ladle, and a tall container metal container. The chef smiled at Lois. “Chocolate ice cream?”
I think you just want to say "a tall metal container."
The steam dissipated and chef tilted the large bowl of ice cream towards her for her to examine. He took a teaspoon full of it and handed it to her. She stuck it into her mouth and moaned.
I think you want to say "the chef".
Clark took the paper and scanned the article. The woman’s body found in the woods, fifteen miles outside the Gotham City’s limits at the end of August, has been identified as missing Metropolis resident, Monique Kahn. He set lowered the paper. “That name sounds familiar.”
Two things. Firs generally it would be Gotham City limits, you usually don't directly make it possessive. Also I think it should probably be "He lowered the paper" or "he set down the paper."
