What is "bermudadreieck"

The Bermudadreieck (Bermuda Triangle) in the center of Bochum is the designation for an area with a high density of bars and restaurants, bounded by (clockwise from top) Südring (South Ring), Brüderstraße (Brother Street), Kortumstraße (Kortum Street) & Viktoriastraße (Victoria Street). The number of gastronomic establishments has increased since the beginning of the 1980s, spurred by the short distance to the Bochum Theater, Union Theater and the main train station. It is served by Engelbert-Brunnen/Bermudadreieck U-Straßenbahn Station, on lines 308 & 318.
