IMO, one of the most prominent thing that catches the eye of new people in the US is the size! Be it the country, the people, the food served or the items available, it is big, bigger and biggest.
Even before coming to the US, I had a lot of Friends & Relatives here. Never paid attention to where in the US they lived, though. So, when we were to move here, I was overjoyed that I would be enjoying their company often. Only after coming here did I realise how vast this country is(it is three times that of India, it seems). I understood that, 'oh, we live in the East coast too' meant anywhere between 10-1000 miles!!
Most people here are of big-built, not necessarily fat/overweight category. Even now it is sometimes hard for me to tell if a guy standing next to me is a teenager or an adult! So, quite a few of my friends of heavy-built(according to Indian stds.) are so happy here that they don't look big and that they find clothes in the normal(!) section!!
If ever one wants to give up a favourite item, they should shop at whole-sale clubs! The items available are in such mammoth sizes that you would wonder if it will get over at all!! The first time I went to such a store, we were urged to stock up as they were of great deal prices! Even after 2 years, I still had some of the items bought during that trip!! A special mention is needed for our cannot-live-without Indian groceries. Both Sambar powder and Turmeric powder will be available in the same size!! What a contrast to our 'potti kadai(s)'!!
Ah, the Restaurants! This is one place where you can have your 'paisa vasool'. For the money one pays, the food served would be so much food and if unable to finish it, can always ask for a doggy bag and save it for the next meal!! I have never managed to finish a medium sized beverage till now!
