First week of my job out in Spain was invited out for lunch with some colleagues and the boss, I asked for some water to drink, every other person there looked at me weirdly and then ordered beers and wine. I was shocked but to them I was the odd one for not drinking, says a lot about the cultural differences!
You could perhaps have mentioned you'd probably finished at 1.30/2 and presumably weren't expected back in the office until after 4 (thus having plenty of time+a good meal to absorb any lunchtime booze).
PS The only time I drink at lunchtime in the week is on a Friday, when my wife and I regularly go out to a local restaurant in SC (and I don't have classes until 4 or 7 pm afterwards).
