I visit tech cities across the US often for work and in comparison I find Austin is incredibly affordable.
Having moved from Boston, not sure what's East Coast about Austin. Certainly not the (lack of) Mexican food.
Also, I must apologize for specifically saying "East Coast" when describing Austin. It's unfair to you and everyone else on the East Coast. Well, mostly unfair. I've spent most of my life on the West Coast and so it was a subtle insult, but you're right, Austin is less like the East Coast than it is like Los Angeles. But one thing is for sure: Austin is nothing like Austin from the 80s, and I am just the messenger for that last statement, having spent most of my time in Austin hanging out with life-long Austinites of lore. So I apologize for the "East Coast" comment. But, I really do want some Chuy's now that you mention it.
