That's funny about the PB crackers because whenever we drive down to the States, we always stop in a Walmart or grocery store before coming home, and always pick up some of the Lance brand peanut butter and honey crackers (amongst many other things, including various flavours of Coke/Pepsi/Dr Pepper, hamburger helper and chicken helper, cheesy garlic bread Lays potato chips and whatever else looks yummy that we can't get in my neck of Canada). I think here in Canada we have Ritz peanut butter sandwich crackers.
After a few weeks in Europe, I am always craving a 'homestyle' meal - I want veggies, potatoes (not french fries), gravy if possible, chicken breast (not chicken thigh/leg like seems to be popular in Europe), a big glass of COLD milk...on our last trip in Oct, the night before coming home, in London we ate at the Stockpot (RIP - they have closed I've been informed) and I was never so happy to have roast potatoes and veggies. For the record, generally on our trips we tend to stick to either pasta/pizza, I may have a salad, or we have burgers.
re - European burgers. In Paris, we stumbled on this little restaurant down a shopping alley (what is the technical term for those?!) and had one of the best burgers I think I've ever had. Mind you, it was mid-afternoon and we were starving so that could have coloured our tastes, but it was made with Saler beef, had some caramelized onions on top and the cheesy dip with the potato wedges was delish! It was just called Buffet Bar and it was on our walk as we were heading towards Galleries Lafayette, down a little alley off Blvd Poissonniere/Blvd Montmartre area. Décor left something to be desired, but the burger lunch deal was great (small salad, burger and roast potatoes and a drink for 10Euro).
On the flip side, last time I went to visit my sister in the UK, we took pop tarts for her daughter (and they survived two weeks in the carry on!). They don't have all the flavours like here. And there are a few other things my mom always takes over - but they aren't coming to mind right now (oh - I think one is Manwich! Also these little flavor packets to mix in with your vanilla icing/cake frosting). I once sent over 10 sticks of deodorant (in exchange for Thornton's fudge...my obsession) because she said most of what they had in the UK was spray and the few choices of stick deodorant she didn't like.
As for travel withdrawal - it's hard for me knowing we won't have another trip overseas until 2017 (our dollar really sucks right now). So I have to content myself with planning a trip to Toronto next spring, but it's certainly not as exciting as planning a trip to Europe...sigh. It helps to work on my travelpod blog of the last trip and relive everything we did!
