Rainbow Bar & Grill Reopens: Come Party with Us! No More Roach Trouble

The legendary Rainbow Bar & Grill is cockroach free according to the owners, who say the Sunset Strip joint is ready to party for Halloween weekend.

A rep for Rainbow tells TMZ they'll open their doors again Friday night after a week long hiatus. The legendary rock 'n' roll hot spot was shut down by the L.A. County Health Department for "vermin infestation."

We're told management has the place spic and span now after removing all roaches and making some kitchen repairs. A rep told us the problems stemmed from the building being so old ... the landmark bar's been open since 1972.

The RBG gained it's fame as a regular hangout for music legends like John Lennon, Neil Diamond and Alice Cooper.
