1. It's a map of "the best", so maybe the default filter shouldn't show "ok" recommendations

2. The numbers on the pins change regularly (I'm on mobile/Firefox). Maybe the pin could indicate the source of the review, or the quality, or the restaurant type? Or not have the number at all.

3. Moving the map around reloads the pins for the viewed area, but it sometimes loads a different set of pins for a big city. Is there a max number of pins being loaded on each map view change? If so, perhaps the max should be higher?

Hope that helps!
