I braved a sushi trailer in June and lived to tell about it. Starting today, I’ll be posting a weekly Trailer Thursday edition of our Eat My Words blog to let you know which food trailers are toothsome and which are tasteless. For my initial foray, I picked one that hasn’t gotten a lot of attention yet: Sushi A-Go-Go, located in the parking lot of a gas station and convenience store in Central Austin. I confess, I expected to find sushi that didn’t quite compare to the prepacked stuff from Whole Foods. But the Japanese couple that owns the trailer serves around thirty fresh, delicious rolls. Of the four I tried, the highlight was the Sunshine—salmon, avocado, and just-ripe mango. My second-favorite was the Surf and Turf roll: tempura shrimp and grilled beef accompanied by cilantro and green-leaf lettuce. Candied jalapeños lining the inside delivered a spicy-sweet kick, but the slightly bland jalapeño mayo topping didn’t impress. My least-favorite was the fake-tasting “krab salad” in the Fat Samurai roll (honestly, what was I thinking—”krab salad”?). But the Rock ‘n Roll redeemed the experience, with crispy shrimp, carrots, and sprouts. Although I could have sat down to eat at one of the picnic tables (with umbrellas) beside the trailer, I took everything home, since the smell of the gas station next door was just a little too hard to ignore. One last tip: Be prepared to wait, or call ahead, as rolls are made on the spot. (Trailer Thursday will report mainly in Austin, where locals are opening more mobile eateries each week than we thought possible. But we’re always on the prowl for new places in other cities or feedback about tried-and-true ones, so add a comment to our site or send us an e-mail.)
