I was just on the Malecon and Centro last week. I think I recognized the square with the Luchadors too, which does not usually have a wrestling ring. Yes, outside of the major thoroughfares most of the city is narrow cobbled streets. I've been on buses that feel like they're going to hit the buildings while swinging around corners. And driving is crazy. It's not real obvious in the epidode where they're going down that main street but the lanes in the middle are like express lanes and you can't exit directly from them, if you want to turn you have to switch to the outer lanes running alongside. Which means lots of jughandles because there are no left turns.
Teams seem okay, no one instantly dislikeable or obnoxious. There should be a tequila challenge, not taking shots but something like chopping up the agave and putting them in the ovens. That's a lot of hard work.
