If you're asking at railway station, then there is only one catering stall. Chips, biscuits, water bottle, vada pav, somasa, cutlet, biryani will be available. Don't know to what extent they're fresh. I once had a plate of vada pav, just OK
If you want a decent hotel, then its 2-3 kms far from satara railway station. There is nothing outside the station.
