Your "choa moljom anmashi gesoyo?" can be written '좋아, 뭘좀 안마시겠어요?" but it sounds a bit odd, so I should change this sentence according to your English version ; 마실 것 좀 드릴까요? ma sil got jom drill gga yo? 저랑 뭘 좀 같이 마실래요? jo rang mol jom ga chi ma sil re yo? 저랑 한잔 하실래요? (Would you like to drink with me?) jo rang han jan ha sil re yo? 저랑 맥주 한잔 하실래요? (Would you like to drink beer with me?) jo rang mek ju han jan ha sil re yo?

Pimsleur is horrible. Learn Korean at talktomeinkorean.com instead. koreanclass101.com is also good but is not free.

try typing some korean actors name and that would defently remeber what you need to.. is really helpful :)

Is there hangeul version of that phrase in that Pimsleur Korean course? I don't mean to be rude about that course or the way they teach.. but... I think... "romanization is such an evil for those who learn a language (with writing not based on latin letters), it's better leave it to linguists and those from academic circles".. It would take a week to learn hangeul (korean alphabet) and another week to fix it in your memory ;) try this http://www.koreanwikiproject.com/wiki/index.php?title=Learn_hangeul ps: not only romanization but any representation of phonetics of one language using phonetics of other language is just wrong.. maybe it's necessary for academic purpose, but if you're going to learn sounds of foreign language through sounds of your native language then you're gonna have bad time (and strong accent) ^^
