A movie and then a restaurant? Jeez that's got to be a long date? Unless its a problem in my game, a meal at the restaurant takes about 5-6 hours in my Sim time. I have to start a restaurant date at around 5pm to get them out of there at a reasonable time! However my Sims do talk a lot. Sometimes its the only way to keep them all at the table.
Try performance venues or museums. Or a Karaoke venue? - Side note - what's with all the Karaoke venues recently? There's like 3 in San Myshuno?
