Hmm.. usually the best course of action if there used to be a game location is to ask in Wayspot Appeals for reinstatement. If it used to exist, it will have been removed for reasons. Staff will have to tell you if an owner asked for it to be removed. If they don’t accept the appeal, then you can try a new submission.
At the risk of sounding like an AI, you’re not talking to Niantic to ask for a gym - you’re trying to convey to reviewers like yourself what is interesting about this place.
I would correct the photo and the description and rewrite the supporting info in your own words sharing only the essential information here - what you want to say there is that it’s a good place to socialize and bring proof why. Here I would recommend including evidence of why this pizza place is more interesting to go to than the next one over. AI tools have no idea what makes good nomination text, and they already made your nomination an outright reject because of the game terms in the description. I suggest being respectful of the reviewers’ time instead of flooding them with irrelevant text.
Oh totally, I’m discussing how to improve this specific nomination in a vacuum. It was unclear to me if this specific pizzeria was a gym or something else in the area. If the wayspot for this particular business was incorrectly removed, then it should be appealable.
