With this and a local version of the page I was able to get the info you want:

#!/bin/env ruby19

require 'nokogiri'

raw = File.read("restaurants.html", mode: "r:UTF-8")
puts raw.encoding
# raw.force_encoding 'UTF-8'
doc = Nokogiri.parse raw

doc.xpath('//div[@class="listing_content"]').each do |listing|
  puts '----------------------------------------'
  # p listing.to_s[0...10]+"..."
  puts listing
  puts '----------------------------------------'
  # p listing.xpath('.//a//text()').map(&:to_s)
  listing.xpath('.//a[@href and contains(text(),"Website")]/@href').each doa|
    p a.value
  end
  puts
end

Cheers
