I'm not sure I want to be drug into these discussions anymore. It seems like such a waste of energy to try and convince people for whom no amount of reason and evidence is ever going to be considered against personal belief, apparent indoctrination and apparent self-appointed expertise in logic, science and the mind of the biblical God.
With that editorial out of the way, I suppose I can give you my opinion based on the reasoning I would use.
1. The man is in the city in question. One would expect that a person that is apparently working and likely a resident of the city a person is in would have a greater chance of knowing local dining choices.
2. The man is local. The expectation would be that a local person would know local restaurants better than one that is not local to the area. Just as I know what is local to my area having frequented those places.
3. The man works in the hotel and restaurant business and the expectation is that choosing someone in that profession would increase the odds that they would know restaurants in the city.
4. Experience teaches most of us that spend any time in hotels that employees there frequently are questioned about local dining choices and have taken the time to know the local restaurants to be able to inform their guests.
It is a claim. It can be tested by seeking and finding the restaurant. It is supported with those pieces of evidence I have listed. But, by itself, it is a claim. If you just asked a random person the same question, much of that supporting evidence would not be attributable to the claim. You can still test it. You may get lucky. But the former, better supported claim should offer the best odds of succeeding.
