The only reason The Alibi survived the 90’s, 00’s and beyond was because of the crowds Karaoke brings in the evening and weekends. Likely still the case now. With such a huge space, you need to people that stay all night drinking and singing, and bringing large groups of friends. Without those people, it would be virtually impossible for a place like The Alibi, in the area of Portland that it is, to make enough money. It’s not a place you just wander to like if it were downtown, it’s a destination. Same principle goes for the lottery machines, there were (presumably are still) so many regulars that come in during the day to play the machines and drink and eat, and the bar’s portion of the the Oregon Lottery‘s payouts typically keeps the lights on at bars, and that’s why places have them.
Plus in my mind, both Karaoke and the gambling lend to the old-school Vegas vibe!
