i'm a recent 'hound transplant from boston, and i could really use some help sussing out the good eating around my new workplace. i've seen some decent indian around 27th & lex, but beyond that, i really have no idea what's chow-worthy and what's crap. i need something within a reasonable walking distance, quick & cheap (& tasty, natch). in particular, i'm trying to find a reliable sandwich place (kind of like my beloved darwin's, back in cambridge), some thai and vietnamese, a noodle joint (chinese, japanese or korean), mexican, and middle eastern. but of course, any suggestions are much appreciated. bonus points if there's either cuban or vietnamese sandwiches nearby.
