We visited the Silverton twiced on our current vacation inorder to take advantage of the happy hour in the lounge/bar of the Twin Creeks Steakhouse. The happy hour runs Tue-Sat from 8-closing and features 1/2 price drinks and tapas. The toasted almond cocktail was like dessert in a glass and only cost $5. Recommended tapas include the dates, trio of bbq prime rib sliders, piquillo peppers and meatballs.
The Silverton is a nice casino with a lot good machines. However, be aware that not only is the buffet pricey, there are also some nights to just avoid it, specifically the Hawaiian Luau night. I made the mistake of paying full price and found the food less than decent. The pig was overcooked and everything else was 2nd rate. I did have my buy one get one free coupon but since I was alone, they wouldn't give me 1/2 price (the logical and accepted norm). Instead they sent me to the players club where I found 100 people in line trying to redeem a free play for locals coupon. I gave up and paid the full price. The cookies were good!
