This review is for 3.5 stars.
I don't like Town Square that much as I typically find it overpriced, but they do have some solid HH deals. Double Helix has a great HH in terms of timing (from open until 7:30pm). A HH ending at 7:30pm is almost unheard of in Vegas. They have a couple of beer and cocktail deals for under $6 and then about 6 appetizers to choose from for around $6-8 a piece. The drink selection was fine - nothing amazing. I had the apple cocktail and enjoyed it but wouldn't pay sticker price of $12. The food was actually pretty average. Portion sizes were very small so coming here outside HH would probably require at least 3 dishes to suitably get full. They have a nice whiskey selection and a few tvs to watch the game, but I think Double Helix is a little classed-up; a bar to the tune of Yard House or McFadden's next door is more in my wheel house.
