No sign that the annoying practice of not listing drink prices in USA restaurants is changing. I was in a restaurant this week that didn't even list the soda prices.
I really wish this would get regulated: otherwise, most restaurants will continue to keep them "unlisted."
And while we're at it, I'm noticing an increasing trend of restaurants having expensive "daily specials." At fancy restaurants, there is rarely a board listing the prices, and the waiters don't volunteer the pricing information. I guess they're hoping you'll be too embarrassed to ask (and it IS embarrassing). The specials are almost always a "worse deal" than the menu items. Ridiculous, but I guess the business is tough and restaurant owners share their revenue tricks.
