I've never used grubhub, but this is shady. In a rush I once had to find and call a hotel and get a reservation. The site I used looked like a typical priceline or whatever- looked legit. Instead of providing the phone number of the hotel front desk, it sent me to some shady hotel booking service. I was tired and probably not thinking straight - but they took my card and the room was booked. After arriving at the hotel I indeed had a reservation, that was nice. What wasn't nice was that it wasn't paid for. I had no idea who I called, and it was super late so I had no options. If I wasn't in a gigantic stressful situation at the time I would have done more to figure out what happened. Not saying that grubhub or yelp is THAT shady, but that kind of business practice is.
