For lunch or late-lunch, Queen Mother. Few City-tv types hang out there.
Downtown Sheraton Trader Vic was a real busy singles pickup bar.
Al Friscos after work is another singles hangout. Food bit over-price but decent. I prefer Montana when their chef is having a good day.
Mentioned in other thread, bar at The Keg on York st is another pickup joint.
Great steak & roast beef.
Outbacks and Baton Rouge are friendly for lone-diners. Try Rouge's Onion bloom.
