scrapy-splash active content selector works in shell but not with spider

I just started using scrapy-splash to retrieve the number of bookings from opentable.com. The following works fine in the shell:

$ scrapy shell 'http://localhost:8050/render.html?url=https://www.opentable.com/new-york-restaurant-listings&timeout=10&wait=0.5'    
...

In [1]: response.css('div.booking::text').extract()
Out[1]: 
['Booked 59 times today',
 'Booked 20 times today',
 'Booked 17 times today',
 'Booked 29 times today',
 'Booked 29 times today',
  ... 
]

However, this simple spider returns an empty list:

class TableSpider(scrapy.Spider):
    name = 'opentable'
    start_urls = ['https://www.opentable.com/new-york-restaurant-listings']

    def start_requests(self):
        for url in self.start_urls:
            yield SplashRequest(url=url,
                                callback=self.parse,
                                endpoint='render.html',
                                args={'wait': 1.5},
                                )

    def parse(self, response):
        yield {'bookings': response.css('div.booking::text').extract()}

when invoked with:

$ scrapy crawl opentable
...
DEBUG: Scraped from <200 https://www.opentable.com/new-york-restaurant-listings>
{'bookings': []}

I've already unsuccessfully tried

docker run -it -p 8050:8050 scrapinghub/splash --disable-private-mode

and increased wait times.

I think your problem is in middlewares, first of all you need to add some settings

# settings.py

# uncomment `DOWNLOADER_MIDDLEWARES` and add this settings to it
DOWNLOADER_MIDDLEWARES = {
    'scrapy_splash.SplashCookiesMiddleware': 723,
    'scrapy_splash.SplashMiddleware': 725,
    'scrapy.downloadermiddlewares.httpcompression.HttpCompressionMiddleware': 810,
}

# url of splash server
SPLASH_URL = 'http://localhost:8050'

# and some splash variables
DUPEFILTER_CLASS = 'scrapy_splash.SplashAwareDupeFilter'
HTTPCACHE_STORAGE = 'scrapy_splash.SplashAwareFSCacheStorage'

And now run docker

sudo docker run -it -p 8050:8050 scrapinghub/splash --disable-private-mode

If i do all these steps a get back:

scrapy crawl opentable
