My early taco experiences were a hodge-podge of authentic and inauthentic, but they came at an age when that didn't matter—I liked it all. These experiences include all-day cooking parties, where the adults (my parents and their friends) prepared food while we kids played, then we all went home and changed for dinner (gives you some idea how long ago this was!), and returned to eat their culinary efforts. The primary friends with whom these parties were held were friends who had a winter home in Santa Barbara, CA, so we did lots of Mexi-Cali foods, including most memorably chiles rellenos and tacos. Then, as dad had started working for United Airlines, we started traveling to California ourselves. A vivid culinary memory from when I was not quite yet a teen was stopping at the Frito-Lay stand in Frontier Land at Disneyland, where they offered tacups -- corn tortillas fried in the shape of muffin-sized cups and then filled with taco fillings -- ideal for folks with small children who might not be tidy with ordinary tacos. Of course, once the packaged taco shells became available, we jumped on that bandwagon, and started having taco nights at home. And when Su Casa opened in Chicago in 1963, we must have been there the first week, as my dad was always pursuing new ethnic restaurants. I don't guess, however, it was until I went to college in California that I started really making distinctions between authetnic and in-authentic tacos.
For other first:
First Greek food was at Diana's Grocery, back when that was the only place to eat in Greektown.
First Cuban was at Columbia Restaurant in Tampa. My dad was born and raised in St. Petersburg, FL, so I was introduced to local specialties (smoked mullet, as well as Cuban food) on our first (and every subsequent) trip to visit his family (long time ago).
First Indian was when I was living in England as a student (1972). Towns too small for a post office would usually still have a good Indian restaurant.
First Indonesian was on a long weekend in Amsterdam, having escaped my studies in England for a couple of days.
My first falafel was that same year, in the market of the Arab quarter of Jerusalem.
My first really great bottle of wine was when I was 16. My dad was (among other things) a wine taster for the Mid-America Club, and he'd brought home a bottle of Chateau Haut Brion Blanc. He made us popcorn, sat us down, and explained what we'd be drinking. Up till then, all I'd had was sips of bad wine, usually at parties where kids were invited or at sampling at the liquor store, and I had not formed a favorable opinion of the beverage. I may have just been a kid, but I knew instantly that this was better, that this was why people fell in love with wine. Now, this knowledge didn't save me from drinking some Spañada and a bit of Annie Greensprings while I was in college, but once I had a career and my own income, I knew what I wanted to spend some of it on.

I guess it's an indication of being a foodie that I remember so vividly so many food firsts. I won't bore you with the first whole cooked fish, the first reuben sandwich, the first montecristo sandwich, the first snails—but suffice it to say that they have all come back to me as I've sat her reminiscing. Lots of fun. Thanks, Cathy2.
