I travelled a lot in my old job and stayed overnight and ate at either the hotel or a nearby restaurant. I have asked often to have bacon and eggs in the morning. This was no problem. The hotels and restaurants have to have a breakdown of the food they are serving. I have actually seen the books and folders containing such information. The nutritional information is there. Ask to see it and ask them to cook fresh, they are so obliging. I have never been refused a fresh piece of meat, fish or salad.
That said, the local pubs are minefields, both of my nearest pubs, have everything brought in to warm up (except the salad) in a microwave oven. The salad is already prepared and arrives in plastic bags with dressing on.
I have to be very careful dining out, so the majority of the year, I cook fresh myself, at home. You then know for certain what carbs you are eating.
