I'm sorry you're getting downvoted, but to explain why I think this opinion isn't popular, look at Amazon. There's an entire sub-economy of exchange for reviews with unspoken rules. Choose about any product and you'll likely find the phrasing "I received a discount in exchange for my unbiased review of this product" or "I receive a demo version of this product in exchange for my unbiased review", or some other similar disclaimer.
There's nothing technically wrong with what's happening there, since there is no formal arrangement of good review = free product, but it's perfectly understood without a single word being said that if your reviews are too critical, you will not be receiving discounts/demo items in exchange for an unbiased review any more.
Your idea isn't quite the same if I understand it since the restaurant isn't enticing people in with the promise of a discount for reviews, but it's hard to say that you're not being influenced for favor when receiving something like that. It's why I believe it's a journalistic ethical standard to refuse gifts/outings from businesses and individuals as it may compromise journalistic integrity. Whether or not that's actually followed or just a super-ideal is another matter entirely
