Downtown
I don't play single deck much lately, but I do go downtown to use the www.casinoperks.com coupons.
Las Vegas Club is the best. It has lots of tables with ok penetration ($5 min.). Don't confuse the automatic shufflers for continuous shuffle machines. Say "Hi" to that cute French dealer, Karine, for me. ;o)
Binions also has a lot of tables with $5 minimums, though not as many as before.
Golden Gate usually has one or two tables.
4 Queens has a table, but they use a cut card that is usually too shallow.
Lady Luck is supposed to a have a single deck game, but I've haven't seen one there for over a year.
Gold Spike has a $2 game.
El Cortez has a few tables, some with $2 minimums.
And then there is the Western. I've dared to go there only once, and that's just so I can say I've played there. It has a few tables. (Are there still $1 minimums?). Go there only during daylight hours.
