Thousands of homes in the UK were left without water on Saturday when frozen pipes burst due to rising temperatures.
The restaurant tweeted live updates about where water had been restored, while distributing bottled water and offering "community toilets".
We are open for anyone to come in to use toilets, take water, fill up water and if you know any vulnerable people let us known and we will deliver it.
Code word WATER for free margaritas #streatham — El Chico’s Streatham (@ElChicosSW16) March 6, 2018 Report The restaurant’s owner Alper Yagmur said: "I was born and raised in Streatham so I took it upon myself to help the community."
Another said El Chico’s had been "the best source of information" and promised to "pop in for a cheeky drink" to say thanks for their efforts.
— Jason Campbell (@jasondcampbell) March 6, 2018 Report A third echoed the sentiment and said the restaurant had offered services that were not "adequately provided by Thames Water".
@ElChicosSW16 are definitely the heroes in the #Streatham #watergate issues going on.
