Cafe U & I is a Karaoke hangout.  The locale opens early evenings and closes early mornings.  You can rent a room for a small group if you don't want to sing in front of  a crowd. 

The song list includes some hit English songs and the latest Korean and Japanese songs. You might want to dine before heading here, there is a limited menu, and alcoholic drinks are not served here.  You'll find coffee, sports drinks, and Korean and American soft drinks. 

By the way, if you're going out with a group it is advisable to carpool.  Parking is limited or rather, difficult, as there are a number of other patrons of other establishments vying to park in limited spaces.  Towing is strictly enforced; and it would be advisable to read signs carefully.
