I am reviewing the Steak Burger on Gran Via, which is so new it hasn't made it to yelp yet. I was…read morelured in by the decor, a cool mix of, chesterfields, Italian modern, and industrial.
The initial service was good, I ordered the BBQ burger without cheese medium rare. Besides the Monterey Jack cheese that I skipped, it's supposed to have BBQ sauce, bacon, grilled onions, & lettuce. The burger was delivered medium well, the bacon was skimpy, and grilled onions were raw. I'm not sure if it was because of being overlooked, the burger was tasteless, the small amount of bacon, and BBQ sauce were lost, all the came through were the onions, which I removed, in an effort to taste the meat.
It was a hot day in Madrid, so I ordered more water when the burger arrived, it arrived well after it was finished. As a former restaurant manager, I watched the three waiters leave the service counter empty handed five times while a waited. The service in Spain is very good, so this is not a cultural thing.
In conclusion, Spanish beef is good, so don't be nervous about trying a Spanish burger joint, just not this one!
