Everything at the LVH, except for the rooms, curiously, is overpriced. Food at the Paradise Cafe no exception, it's totally average, and totally overpriced. Fact that there are no real food alternatives within a short walking area, must make the money counters at the LVH smiling.
Stay here, you really can get some great room prices, but eat elsewhere, unless you have money to burn and you don't really care...
