Spotted by Locals is a great resource to find places off the beaten path where typical websites or guidebooks might not take you. I have used it in multiple cities in the USA and Europe - such as San Francisco, Seattle, Washington DC, Prague, Munich, Athens and Istanbul - and each time I have found places that have been a highlight of my trip. The city guides are cheap and the offline maps make it well worth the investment.
