A great restaurant in Manteca (between Livermore and Modesto....many drive through Manteca on their way to Yosemite.)
Anyway....a great restaurant is Isadores on Main Street. They start everyone out with a cheese fondue. Dinners come with salad or soup and the entrees are delicious. They have fresh fish, prime rib, steak, duck, lamb and much more. Everything is tasty and the desserts are fantastic as well. They have a great Bananas Foster and are known for their "Sex in a Pan".
Isadores is really worth a visit. I'm not associated with Isadores in any way except as a satisfied customer.
