I'm would like to introduce the group to a dining-socializing option at the Gold Spike(half a block from Denny's).They don't have gambling here, but they do have lots of free games indoor and out,like over-sized chess,pool,beer pong,corn hole,octopong,etc..They have order a burger,salad,sandwich,etc...at the counter kind of dining,a large bar and a big living room kind of space with couches and easy chairs.
This is also the kind of place we can meet at if the weather isn't very nice or you just can't take the loud noise on Fremont St.
The best parking I've found is under Denny's restaurant.Get there by going north on 4th and veer right after passing Denny's and down the ramp.The first hour is free and $1 an hour with a max of $5 in 24 hours.
