casual restaurant

I went to a restaurant where it was pretty casual about where and what you ate. They had a big meal out in the center of the table and you could sit down and take some. I stood awkwardly for a bit but then sat down and took some. I think it was cheesy and gooey. I had a water as well. But there were a lot of waters around. I had to double check a lot. The guy beside me thought he had my water because it was more salty. I was puzzled by that.
