If Red Hook vendors want to cook at the ball fields, they’ll have to use approved food-preparation carts, according to a report in the Daily News. The city Parks Department is now accepting bids from vendors, but the traditional mom-and-pop stands may not be able to afford the upgrade. Plus, are those carts even suitable for the kind of deliciousness served in Red Hook? One vendor, who requires four grills to make her pupusas, says no: “We’re not just boiling hot dogs.” You said it, lady. The city will award vendor permits at the end of February.
