We have traveled twice during this pandemic. We take precautions, wear masks in confined spaces, make sure we are vaccinated and current boosters, avoid large crowds...and that is about it.
Current evidence suggest that if properly boosted, and despite taking extensive precautions, you can still get covid, and a decent chance of it. The good news is, properly boosted, your symptoms will likely be mild, you may not even know you have it.
To that end, it is your choice, but I would have no qualms about eating in most restaurants, and I certainly would not resort to eating in my hotel room for any significant number of meals. It comes down to a personal choice, but if I started to eliminate things I like to do while traveling, I would first reconsider even going.
