Regarding BBQ in the US, regional taste plays a big part in preparation and taste. There are a lot of chains and restaurants that claim 'Texas BBQ,' but honestly have nothing in common other than the name. It is not Texas BBQ unless a flavored wood is used in preparation, normally mesquite, and uses an actual pit/closed grill. In fact there are a number of of so called chains that use 'Texas' in the name yet are completely unaffiliated with the state. Some locals even fall for the ruse, but I know my BBQ, and only eat at local eateries. Though in their defense many adopt local preparation techniques once they get here or they don't last.
As for Australian beef, it's good meat, I have done a fair bit of traveling and its worth the money. The best steak I ever ate, and I have eaten my share and paid good money as well, was at an Outback in Dubai... of all places; an Australian strip preprared by an African chef... it was amazing. Granted in the UAE a immigrant can be deported for bad service, so food was always good. But, this was an amazing steak and I have had Kobe steak while in Japan, prepared by a master chef. I couldn't stop eating or laughing at the table, everyone thought I was nuts, but they all got burgers; which they said were really good. I was straight-up manical lord... fools.
Anytime I have out-of-towners, I always give them a list of good burger joints and steakhouses to eat at, because the best part of traveling is the food. Texas, steak, burgers and beer; what else is there in life? I get upset with people who travel halfway across the globe and then eat at a McD's... why? Eat at a local place, I always ask a local where's a good steakhouse and a good lunch joint.
That aside best ramen I ever ate was a place called Nama Ramen, local eatery, definition of a whole-in-the-wall/greasy spoon, started by a Japanese immigrant. I spent three years in japan, and the best ramen I have ever eaten is in Texas. Go figure.
