Google announced on Google+ that you can now search restaurants in your area and now even filter by price, ratings, cuisine and hours of operation. I am not sure if this is a really new feature but if you haven't used it, it is well worth using.
Here is a screen shot:
It’s hard to make last-minute hotel and restaurant reservations in your price range, in the right neighborhood and with the right flair. But now, you can just ask a quick question on your phone—tap the mic on your Android and say “show me some restaurants in downtown Austin.” You’ll see your options and you can swipe to see more, or tap the button to “see all.” If you need a way to make sense of the many options, tap the new filter tool to help you narrow it down by price, ratings, cuisine, and even whether it’s open now. (This works only in the U.S. for now, but stay tuned!) Found the one? Just say “OK Google, call 219 West” and you’re good to go.
