I was up in SB yesterday for business and scheduled my whole day basically around stopping in at LSR. Every time I'm in town, I try to make a point of eating here. Crushingly, I arrived to find that they're not open on Wednesdays...ended up trying out Los Agaves, a Mexican grill which is about a block south down Milpas toward the 101, and I'm really glad I did. The place was absolutely packed at about 2 PM, but after getting through the line and finding a table, my order arrived in just about 5 minutes. The sorrow of no La Super Rica was soon tempered by a fantastic al pastor pork, rolled into a grilled tortilla with melty, soft white cheese and pineapple chunks. Topped off with their smoky brown chipotle salsa, it was sublime...sweet, smoky, savory, cheesy. The rest of the menu looked impressive and I will definitely make the time to get back here (as well as hitting up LSR on a day other than Wednesday).
