The pizzas where I am from are quite affordable, a name brand pizza chain pizza will cost you about 4 or 5 dollars (currency exchanged) or, 6 or 7 dollars at most if you buy from a independent owned parlor (which i prefer). Alcohol is also quite cheap as well. What is your favourite alcoholic beverage? As stated, mine is Soju, Sake, or a hard seltzer. The only beer I enjoy drinking is one of the Sapporo brand.
Still, I think you should drink less, 4 beers is a lot.
