Regarding taxability of restaurants?

hello sir/madam,
I have a query that if any hotel has room, which has a declared tarif is less than 7500 Rs. then food served by it will be taxable at 5% with no ITC. if such hotel is providing a party hall, rent of which will be taxable at 18% and if food (via indoor catering i.e by that hotel itself) is provided. Will the food taxable at 5 %? because there is no outdoor catering services provided by the hotel?.
