This has also been reviewed before here on CRT, starting with
DannyZee's 2005 review and most recently
WiltTheStilt's 2008 review. It is also already on
LikeMike's "RESTAURANTS - CRT FAVORITES - master list**". Where it hasn't been added yet, and probably should be, is the CRT VIP Map. It is real easy to find. Just head east towards San Pedro. Shortly after Avenida 2 merges with Avenida Central, you'll see Bagelmann's on your left (that is a commonly used landmark for that part of town and IS already indicated on the map). Turn left there and Olio's will be 2 blocks up on your right just as you get to the train tracks. I forget if they're located immediately before or immediately after the tracks but I THINK they're just past them on the corner. Maybe somebody can confirm that so that Archie and El S can place the icon correctly the next time they update the map (btw, the Intensa language school, a block further up on the left, and Whappin', another good Barrio Escalante restaurant around Ave. 13 and Calle 23?, should both probably be added too and El Sultan moved to the other side of Avenida 2).
Thanks to Shadowman for bumping this up and reminding us about this really great SJ dining option.
