Yes, it is in a very safe and well-lit area of the city. Overall, it's very safe to travel to Philadelphia. Although it is said to be one of the most dangerous cities in the United States, this only applies to dangerous parts of the city, which are rarely frequented by tourists. The Rittenhouse area of Philadelphia is one of the busiest and safest areas in the city, especially during the day, but also at night.
You can stroll down Walnut Street in and out of the shops, as some of them close at 8 pm or 9 pm. In the square itself, you'll find Devon, Rouge and Parc, while other restaurants such as Dandelion, Village Whiskey and Pietro's are just a short walk away. For wine drinkers, you'll want to head to Tria Café, while those looking for beer, good food and swimming pool will want to go to Good Dog. Rittenhouse Square is particularly beautiful during the colder months in the afternoon and evening, when lights adorn the park and trees.
