Get a burger at the Hume Lake Christian Camp.  Not great, but edible and price wasis good.

Eat Pizza at the pizza shop at Grants Cove.  Excellent pizza and well priced

Eat Dinner at the Grants Cover Restaurant. Kinda pricy but worth it

Three Rivers currently has four active restaurants and at least seven closed ones. The "good" restaurant in town is the Gateway ( right at the entrance to the park. It overlooks the confluence of the Middle and East Forks of the Kaweah River. Very pretty and the food is fine. The Pizza Factory offers tasty and economical family fare. Ther is also Serrano's Mexican Restaurant. They serve a lot of fish but no margaritas.  The food at River View Restaurant & Lounge is also acceptable.
