We were in Door County for an event, and had been advised that the White Gull Inn was a great choice for a breakfast. We tried it on a nice day in July, so the wait (45 minutes) was no issue. We strolled down to the water (about 2 blocks away) and strolled back and our table was ready (25-ish minutes). We had a party of 5, and I tried the cherry stuffed French toast... and wow. I'm not a huge fan of french toast in general - but this didn't even need any butter or syrup - spectacular on it's own.
Everything else was very good as well; including the service. We would definitely eat here again and strongly recommend a visit for breakfast while in the area.
