Burritos, quesadillas, tacos, nachos, and salads--created at the counter, to your liking--are the staples at Salsarita's, the latest "fresh Mex" chain-dining establishment to open in the city. Get in line, try to sort out the (rather large) menu while you wait, and move through the fixin's stations, assembly-line style, until your order is complete. We ordered a grilled shrimp taco salad, with plump, mild shrimp, black beans, salsa, and sour cream served on a bed of shredded lettuce--filling and satisfying, though we could have done without the deep-fried taco-shell "bowl" the salad is served in. We'd probably have preferred it be served with some lightly salted corn chips, such as the ones served as a side with salsa ($1.99) or the artery-clogging queso ($2.49). Grilled chicken soft tacos were a sloppy treat ($2.29 each): flour taco shells filled with grilled white-meat chicken doused in a mild sauce, topped with cheddar and sour cream, hearty but not overbearing. We won't be ordering the ground beef hard-shell tacos ($2.29) again, though. The oily, bland ground beef spooned into a flavorless corn shell and topped with a bit of shredded cheese was not our idea of fresh--and certainly not delicious.
