jeez, i can only conclude most of you don't know good drunk food...
kudos to lamajuns definitely, whether in berlin, nyc, or ldn, a sureshot! i find that often a doner (or gyro, schwarma, whatever...) is too big and greasy and you feel sick afterwards, whereas a lamajun (or two) tends to go down just right w/ not too much grease...
yunno, i am just not that crazy about poutine... given my druthers in montreal, i'll take a smoked meat sandwhich as drunk food... actually that is one of the best feelings on eart, sitting down in schwartz's blitzed at 1am and getting a smoked meat sandwhich, fries, and some pickles... also, a hot bagel or two right outta the oven from the spots on st. viatur is pretty golden, too...
street tacos are pretty high on the list... good pizza is also a solid yes... a good diner or coffee shop (turkey club and fries, do they have club sandwhiches in england? i never noticed before...) is also a go... also, sometimes a big breakfast (eggs, bacon, potatos, toast) is the best thing before bed...
zhao, i never been to the spot you are praising... on the west coast i def vouch for the 24 hr carne asada burritos spots, tho... fast food wise, i do love how you can get chili on everything in socal...
a nice real deal hamburger (corner bistro, maybe) also does the job...
