We have eaten at both. We might be the only ones who were less than impressed with the food at Homecomin'. The chicken was okay. The mashed potatoes were runny (had to eat with a spoon) and tasted funny. Didn't like the seasoning at all. The biscuits were loaded with cheese, which was okay with me but my husband hates anything with cheese in it! We were overcharged for it too, to add insult to injury.
However, we ate at the Boathouse for our anniversary dinner, and it was fantastic. Great service, excellent food prepared to perfection, and interesting surroundings. I think kids would love the boathouse atmosphere with the aqua boats outside. There were many families of all ages there. I would highly recommend Boathouse over Homecomin' anytime.
