We’re not Mets fans or anything, but Gael Greene’s (Web-only!) scoop that David Pasternack of Esca was planning a Fish Shack for Citi Field has really got us in a Flushing frame of mind. Pasternack told us the new Fish Shack would feature “simple stuff” like fish-and-chips, fried clam sandwiches, and lobster rolls. As at other Citi Field concessions, you’ll be able to see the game while you wait. So what makes Pasternack’s menu special? “I don’t know yet,” the chef told us. “But it’s going to be really good.” Pasternack also hears that there will be a Shake Shack at Citi Field, the same rumor we told you about in August. Is this going to be the greatest stadium food court ever or what?
