Complimentary meal in newly opened hotel 'Onesta'

I had been to newly opened hotel today, thats 'Onesta' in my home town Mangalore in India, which has unlimited portions of pizzas, short eats, starters, lasagne, pasta, deserts and beverages. Food is really really good and it's really cheap as well. So 10/10 points. It was a complimentary meal, I mean everything free of cost, since it was a promotion to attract customers
