Who has them? I noticed them at Gold Coast, and I played them for hours. Turtleman once mentioned they had the lowest house edge on side bets, and with my experience, I can definitely believe that. You get paid 2:1 if your first two cards and the dealer's top card combined equals 19 or 20 and 3:1 if it's 21. Since these numbers show up often in BJ, it sure makes for a fun time! There are several other 50:1 etc combos and I got one of them twice (too bad I only placed $1). Lucky Lucky is distinguished from Lucky Ladies (a very different side bet) http://wizardofodds.com/games/blackjack/appendix/8/#luckyladies. Played this side bet before? Where else is it besides Gold Coast (I hear it's also at Encore)?
