Under Hats Off column in Northwest Gay Review, by Ken Felks on page 14: Hats off also to Jim and Tony two of Seattle’s Bar owners. They have branched out to Portland with two new bars. The LONDON BRIDGE, a very large and beautiful lounge with formal dining and a banquet room with seating capacity for 100 of Portland’s Gayest. And, THE STONE BALLOON TAVERN, both in the Regency Inn, 1410 SW Broadway.”
