If you're at Horseshoe and want a quick bite this is really your best, and for the most part, only choice.
They have a number of sandwich and salad options along with big cupcakes... I opted for just a vanilla latte and it was pretty darn good and only mildly over priced. The cashiers are a little disgruntled but if I worked in a stowed away corner in a casino, I'd have a little trouble putting a smile on too.
