I'm interested in carryout standouts near my job. I've got one. It's the chicken kabob sandwich at Stoupsy's in International Square. The pita is nicely grilled, the chicken is marinated and juicy, the yogurt sauce, feta, onion, lettuce and tomato are ample but not overpowering. All in all, it's quite delicious and a bargain for about 5 bucks. Plus -- and this IS a plus for me but might not be for more ravenous hounds -- the portion is moderate. Filling but not stuffing.
Speaking of chicken, the chicken tikka sandwich at Naan and Beyond on L Street near 17th is also good, but order it without the mayo (miracle whip, perhaps?). The mint and mango sauces are very tasty and are accompaniment enough. The portion is large (I actually find the chicken chunks a little too chunky; smaller pieces would be easier to manage, which is why I prefer the Stoupsy's offering) and it's under six bucks.
SO, anybody have any suggestions? I'd particularly like to know about good tuna sandwiches (other than the very good tuna and feta in pita at the greek carryout on 19th between L & M).
