Food recommendations for broke college student

I study at a potta college in vizhinjam. And by the time the college gets over, i'm hungry as I don't carry lunch. Can anybody pleaseeee recommend some underrated food spots and cafes near vizhinjam, kovalam, thiruvallam, venganoor etc. you get the area i'm tryna convey right? But the catch is it should be affordable AF (broke obv) and should be tasyyyyy!!
