Char No. 4 chef and genuine Texan Matt Greco makes good use of his basement smoker and new patio on Wednesday nights through Labor Day. That’s when he serves a $22 barbecue plate, featuring three meats (a rotating selection includes spare ribs, chicken, pork, brisket, and beef links), two sides, a draft beer, and a one-ounce whiskey pour (196 Smith St., nr. Baltic St., Cobble Hill; 718-643-2106).
