At the end of this month the margarita machines will be silenced and the neon sombrero lights turned off at Gonzalez y Gonzalez, a South-of-the-Border nightlife haunt open since 1989. Owner Ark Restaurants announced the news to the staff last night and issued a press release today, explaining, "The reasons are long, but the short of it is that the lease to the space ended." There's still time to say your goodbyes to cheap happy hour drinks, taco chilangos and no-cover salsa dancing. 625 Broadway, near Houston, (212) 473-8787.
