There is no such thing as stability in the restaurant biz , especially among those restaurants unwilling to change with the times. That's a big part of what makes the three-decade run at Tropics so special. If they've updated their menu, décor, or clientele since the '70s, there's no sign of it. What may be Wilton Manors' eldest gay establishment soldiers on, filling nearly full houses' plates with relatively inexpensive and really excellent steaks, fine cuts of salmon, delicately seared burgers (available only at the bar — try with Gouda), and a classic preparation of osso buco. Tropics' waiters pride themselves on serving the cheapest, strongest drinks on Wilton Drive and on possessing maybe the most dedicated customer base in Broward County. They're probably right on both counts. Tropics brings in the same old queens, night after night, for years and years. They figure: Why go anywhere else?
