Forget grouper sandwiches. In the Keys they're as common as drunken fishermen and usually as boring. Offering a break in the culinary monotony along the southern stretch of U.S 1 is Steve Ehler's Time Out Barbecue, a roadside attraction that serves up some of the smokiest and most tender barbecue in South Florida. The secret, Steve explains, is in the slow-cooking: more than ten hours. Our favorite, the melt-in-your-mouth shredded pork sandwich, is served on a hamburger bun and is topped off with delicious, not too-creamy coleslaw and sweet baked beans for about four dollars. Chicken and rib platters big enough for two go for about $11. Time Out Barbecue has moved from the white lunch wagon with a pig on the side to an indoor structure, and Steve is smoking seven days per week from 11:00 a.m. until 10:00 p.m., rain or shine.
