I didn't know there was a chilis in London! Have you been there? Have you been to a USA based Chilis and if so are they the same? What are the prices like?
I know there are Outback steakhouses in England also. There's one in Brum but I've never been there.
I went to Chili's in Cambridge back in '98. My friend had been in Switzerland all summer and was desperately craving Mexican food. We just took a train from London for the day and one of those hop-on, hop-off "Big Bus" to get in the sightseeing quickly. We hopped off where there was supposed to be a local Mexican restaurant, but it alluded us.
We ended up in this shopping centre that was just like any mall anywhere. Lo and behold, there was Chili's. Texas margaritas, the same menu as far as I could tell. The food was the same. Kids were "cruising" in Mercedes, Jags and BMWs around the car park outside. After 2 margaritas and 2 beers each we forgot that we weren't at a mall in Columbia, S.C. or Atlanta, and didn't have to worry about how we were getting home. It was surreal. I think I went to Chili's here once after that, around 2000 or so?
I found the UK website with the menu and prices here though:
