Your delivery options should never be limited, unless Gabrielle Union orders you to limit them to Deliver Us from Eva, and you're too timid to tell her you prefer her work in She's All That without moral support from LL Cool J. Here to make your food-delivery options "all that": GrubHub.
Established in cities from NYC to LA but still in its ATX infancy, GrubHub lets you e-order/pay for pretty much any damn grub you want, with options searchable by address, city (hey, Pflugerville!), or cuisine (from sandwiches to Vietnamese), and results tweak-able by newness, order minimums/delivery fees, and whether coupons are offered -- helping those aspiring to appear on Extreme Couponing fulfill their other dream of becoming a shut-in. Once settled on a spot, simply click items off its online menu, add any special instructions ("add mayo"; "add OJ Mayo, hope he doesn't wreck team chemistry"), and pay through GrubHub with your credit card; all info's secured tighter than "that ancient temple at the beginning of Raiders of the Lost Ark", giving you just one more reason to be thankful that Harrison Ford is now 84yrs old.
They're running actual-human customer service 24/7, and also just started up a play-by-ordering game offering prizes from a free drink to free food for a year, called Yummy Rummy -- and of course as with any challenge, you should meet it by getting your girlfriends to hoist you atop a human pyramid, and saying "Bring it on!"
